Democrats on the House Judiciary Committee issued a stern warning to President Donald Trump on Thursday: "If you shut down or throttle" the investigation into Russian meddling led by special prosecutor Robert Mueller, "you will plunge this country into a constitutional crisis."

New York Democratic Rep. Jerry Nadler continued, "Mr. President, we are watching you. The American people are watching you."

Many House Democrats called for legislation to protect the special counsel to be included in the spending bill Congress must pass by Friday to keep the government running.

Republicans didn't agree to the measure, however, and the provision was not included.

Asked if firing Mueller was a "red line" that could lead to impeachment, Rep. Nadler stopped short of predicting the consequences, saying only, "all options would be on the table."

Nadler said the firing of the special counsel would lead to a "sea change in the political landscape of the country," that would cause Republicans "to be moved to act" against the president, too.

But he said, "We're not there yet."

Seeking a bipartisan compromise to avoid a government shutdown, President Donald Trump suggested on January 9th 2018 that an immigration deal could be reached in two phases - first by addressing young immigrants and border security with what he called a "bill of love," then by making comprehensive changes that have long eluded Congress.

Trump held a lengthy meeting with Republican and Democratic lawmakers seeking a solution for hundreds of thousands of young people who were brought to the U.S. illegally as children.

In 2017 Trump ended the Obama-era Deferred Action for Childhood Arrivals program, which shielded more than 700,000 people from deportation and gave then the right to work legally in the country. He gave Congress until March to find a fix.

The president, congressional Republicans and Democrats expressed optimism for a deal just 10 days before a government shutdown deadline. Trump expressed a willingness to be flexible in finding an agreement.

Trump told the bipartisan group of 20 lawmakers that if they reach a deal, he will sign it.

A group of journalists observed the meandering meeting for an extraordinary length of time - about 55 minutes - that involved Trump seeking input from Democrats and Republicans alike in a freewheeling exchange on the contentious issue.

The president said he would insist on construction of a border security wall as part of an agreement involving young immigrants, but he said Congress could then pursue a comprehensive immigration overhaul in the second phase.

House Republicans said they planned to soon introduce legislation to address border security and the young immigrants. Trump said, "it should be a bill of love."

President Donald Trump denied January 12th via Twitter that he said anything "derogatory about Haitians" during an immigration meeting at the White House on Thursday, as the country and the world continued to express outrage over his reported comments.

Trump was in a closed meeting with members of Congress to discuss immigration on January 11th when he reportedly questioned why the U.S. would accept more people from Haiti and "shithole countries" in Africa, rather than places like Norway.

At first the White House did not deny that the remark was made. On Friday the president tweeted that his language was "tough" but insisted he did not say anything derogatory about Haitians aside from noting it's a poor country.

Associated Press White House reporter Jonathan Lemire said no one at the White House denied "that he used these vulgar terms to describe these immigrants."

on January 12th Trump took to Twitter to say the language he used at the meeting "was tough," but insisted the words being reported "was not the language used."

He also denied saying "anything derogatory about Haitians other than" that Haiti is "a very poor and troubled country."

***

After President Trump made disparaging remarks about immigrants, some members of the Haitian communities in New York and Florida said they were offended and believed his comments were racist.

President Donald Trump on January 12th questioned why the U.S. would accept more immigrants from "shithole countries" after senators discussed revamping rules affecting those from Africa and Haiti, according to people briefed on the conversation.

Haitians in New York and South Florida reacted negatively to the remarks.

"His comment is divisive. It's un-American. It's extremely offensive. I was reading the Daily News earlier this morning. Actually they could not have said it any better," said Gerald Cajust, referring to a crude depiction of the President on the front page of the New York Daily News.

In North Miami Beach, Florida, hosts at a Haitian-American radio studio, said although they were disappointed in Trump's comments, they believed Haitian leaders were also to blame for the country's economic situation.

Fabiola Charles, a Haitian radio personality with WSRF AM, said "we're looking at ourselves as well and saying you know what, if we took time to actually take care of our people, the president wouldn't have to say something like this about us. So, we also put the blame on us."

US President Donald Trump said on January 14th he is not a racist, just days after making controversial comments about Haiti and African countries.

Trump has been accused of using a vulgar word to describe African countries during an Oval Office meeting the previous week with a bipartisan group of six senators.

People briefed on the conversation say that during the meeting the president also questioned the need to admit more Haitians to the US.

The individuals spoke on condition of anonymity because they were not authorised to describe the meeting publicly.

Trump addressed the issue briefly on Sunday as he arrived for dinner at one of his Florida golf clubs with House Majority Leader Kevin McCarthy of California.

Asked what he thinks about people who think he's racist, Trump said: "I am not a racist". He told reporters: "I am the least racist person you have ever interviewed. That I can tell you."

He also praised authorities in Hawaii for taking responsibility for the blunder that caused more than a million people to fear that they were about to be struck by a nuclear missile.

***

Haitians showed their anger over vulgar comments made against their country and Africa by US President Donald Trump with a protest January 18th outside the US Embassy in Port-au-Prince.

Demonstrators gathered outside the gates of the embassy complex chanting slogans and waving signs denouncing Trump over his remarks and a move to end a program that gave temporary legal status to thousands of Haitians in the US.

Signs and Creole chants by the protesters criticised remarks by the president last week in which he is said to have profanely disparaged African countries and asked why the US would want more Haitians.

The protest by fewer than 100 demonstrators was peaceful and ended without incident.

Another demonstration was planned for next week.

The Haitian government said it was shocked by the remarks, which came on the eve of the anniversary of the country's devastating January 2010 earthquake.

The Trump administration has said that about 60,000 Haitians who have been allowed to stay and work in the US since the earthquake must leave the country in July 2019.

A former top adviser to President Donald Trump's election campaign pleaded guilty to federal conspiracy and false statements charges February 23rd in the special counsel's Russia investigation.

The plea by Rick Gates is a strong indication that he is planning to cooperate with special counsel Robert Mueller's investigation as it continues to probe the Trump campaign, Russian election interference and Gates' longtime business associate, Paul Manafort.

Gates, 45, of Richmond, Virginia, appeared at the federal courthouse in Washington for his plea agreement hearing.

A court filing shows Gates has agreed to plead to charges accusing him of conspiring against the U.S. government related to fraud and unregistered foreign lobbying as well as lying to federal authorities in a recent interview.

Gates' decision to admit to the crimes comes a day after a federal grand jury in Virginia returned a 32-count indictment against him and Manafort, Trump's former campaign chairman, accusing them of tax evasion and bank fraud.

The indictment in Virginia was the second round of charges against Gates and against Manafort, who has denied any wrongdoing. The two men were initially charged last October with unregistered lobbying and conspiring to launder millions of dollars they earned while working on behalf of a pro-Russian Ukrainian political party.

Gates' decision marks the fifth publicly known guilty plea in the special counsel probe into possible collusion between the Trump campaign and the Kremlin during the 2016 campaign.

America's top diplomat is one of any White House's highest-level cabinet members, often seated at the right hand of the president.

As a newcomer to Washington politics, former Exxon Mobile CEO Rex Tillerson was tasked with steering the ship of state with no foreign policy experience and needed to navigate a turbulent, frequently contradictory White House.

As he stepped into the State Department for the first time, Secretary of State Tillerson appealed for unity.

"I know this was a hotly-contested election and we do not all feel the same way about the outcome, " he said, adding "we cannot let our personal convictions overwhelm our ability to work as one team."

But as Tillerson neared the six-month mark on the job, he was forced to knock down a flurry of speculation that he was unhappy and may quit.

At the time, Washington was buzzing with rumors that he would leave due to frustration with the White House.

In his first appearance in the State Department briefing room, Tillerson reiterated that he had a good relationship with the president.

While Tillerson was redefining foreign strategy under the Trump administration's overarching police of "America First", his efforts to craft coherent policy were frequently upended by a tweeting boss.

By October 2017, Tillerson was forced in an unscheduled news conference held at the State Department to defend remarks he made in the Pentagon earlier that President Trump was, "a moron."

In response, Trump said in an interview published in Forbes magazine that if Rex Tillerson did call him a moron, the two should "compare IQ tests."

The White House later said that Trump was joking when he appeared to question his secretary of state's intelligence.

White House Press Secretary Sarah Huckabee Sanders told reporters that the president "never implied that the secretary of state was not incredibly intelligent."

She says: "He made a joke, no more than that."

From the start of his tenure, Tillerson's selection raised potential conflict-of-interest issues, as Exxon's business interests around the globe, included Russia.

As an oil executive, Tillerson had argued against sanctions that the U.S. and European allies imposed on Russia after it annexed the Crimean Peninsula from Ukraine in 2014.

President Donald Trump says he has "total confidence" in Mike Pompeo, his new pick for Secretary of State.

Trump fired Secretary of State Rex Tillerson on March 13th, saying he would nominate CIA Director Mike Pompeo to replace him.

It's a major staff reshuffle just as Trump dives into high-stakes talks with North Korea.

Trump announced the change in a tweet early on March 13th just four hours after Tillerson returned to Washington from a trip to Africa.

He stopped to take questions from reporters at the South Lawn of the White House about his decision to oust Tillerson and replace him with Pompeo.

Trump said he and Tillerson "disagreed on things" like the Iran deal.

"We were not really thinking the same," Trump said about Tillerson. "With Mike Pompeo, we have a very similar thought process. I think it's going to go very well."

CBS says it will air its interview with porn actress Stormy Daniels on March 25th's episode of "60 Minutes."

Daniels, whose legal name is Stephanie Clifford, has said she had sex with Donald Trump before he became president. She has been trying to invalidate a nondisclosure agreement she signed days before the 2016 presidential election so she can discuss her relationship with Trump, which she said began in 2006 and continued for about a year.

CNN anchor and "60 Minutes" correspondent Anderson Cooper recorded the interview with Clifford earlier this month.

Clifford's attorney, Michael Avenatti, told The Associated Press on March 21st that more details of the affair would come out on "60 Minutes," and said his office was checking out similar claims from six women who had come forward.

"This is about this woman wanting to be able to tell her story to the American people, tell her version of the facts" said Avenatti.

"I don't know how serious they are taking us at this point. I think they're probably taking us more seriously today than they were a couple weeks ago. I'll say that. I'll say that they should be taking us very seriously."

Facebook CEO Mark Zuckerberg disclosed Tuesday his company is "working with" special counsel Robert Mueller in the federal probe of Russian interference in the 2016 presidential campaign - and working hard to change its own operations after the harvesting of users' private information by a Trump campaign-affiliated data-mining company.

The founder of the social media giant publicly apologised for his company's errors in failing to better protect the personal information of its millions of users, a controversy that has brought a flood of bad publicity and sent the company's  stock value plunging.

He seemed to achieve a measure of success: Facebook shares surged 4.5 percent for the day, the biggest gain in two years.

Zuckerberg told the Senate Judiciary and Commerce committees that he has not been personally interviewed by Mueller's team, but "I know we're working with them."

He offered no details, citing a concern about confidentiality rules of the investigation.

Earlier this year Mueller charged 13 Russian individuals and three Russian companies in a plot to interfere in the 2016 presidential election through a social media propaganda effort that included online ad purchases using US aliases and politicking on US soil. A number of the Russian ads were on Facebook.

During Tuesday's at-times-contentious hearing, Zuckerberg said it had been "clearly a mistake" to believe the data-mining company Cambridge Analytica had deleted user data that it had harvested in an attempt to sway elections. He said Facebook had considered the data collection "a closed case" because it thought the information had been discarded.

Facebook also didn't alert the Federal Trade Commission, Zuckerberg said, and he assured senators the company would handle the situation differently today.

He began a two-day congressional inquisition with a public apology for the way Facebook handled the data-mining of its users' data. He took responsibility for failing to prevent Cambridge Analytica, which was affiliated with Donald Trump's presidential campaign, from gathering personal information from 87 million users.

"I think he went a long ways toward giving the kind of assurance that Facebook certainly wants to come out of this kind of hearing. I don't think he was nicked too badly," said David Levine, a professor at the University of California Hastings College of the Law.

Separately, the company began alerting some of its users that their data was gathered by Cambridge Analytica. A notification that appeared on Facebook for some users Tuesday told them that "one of your friends" used Facebook to log into a now-banned personality quiz app called "This Is Your Digital Life." The notice says the app misused the information, including public profiles, page likes, birthdays and current cities, by sharing it with Cambridge Analytica.

"Mark Zuckerberg had a tall order today. He really had a lot to get done, which is he had to assure members of the Senate that Facebook was on top of the problem, that they had apologised, that they understood the scope of the problems, and that Facebook was taking significant measures to correct those problems. Mr. Zuckerberg also needed to reassure the billions of users around the world that the safety and security of users' data is paramount in the minds of the top officials at Facebook and that they want to make sure that it's as protected as possible."

"He was very good at looking sincere the way he needs to, looking contrite, making eye contact when he needed to, looking down when he needed to look a little 'I'm hearing you' that sort of thing, so he certainly looked coached. He looked sincere. He looked like he wanted to work with the senators. But he also held his position. If there were issues about will you support a certain type of legislation, where obviously Facebook doesn't really want to support it, he said 'well I agree with the general principle and certainly our team can work with your people,' but when they tried to corner him about 'will you support certain legislation' he wouldn't do it."

But by and large I think at Facebook headquarters they're going to say, certainly at the end of today, there are still more hearings, but - mission accomplished."

4. SOUNDBITE (English) David Levine, law professor, University of California Hastings College of the Law:

"Mark Zuckerberg had a tall order today. He really had a lot to get done, which is he had to assure members of the Senate that Facebook was on top of the problem, that they had apologized, that they understood the scope of the problems, and that Facebook was taking significant measures to correct those problems. Mr. Zuckerberg also needed to reassure the millions of users around the world that the safety and security of users' data is paramount in the minds of the top officials at Facebook and that they want to make sure that it's as protected as possible."

"He was very good at looking sincere the way he needs to, looking contrite, making eye contact when he needed to, looking down when he needed to look a little - 'I'm hearing you' that sort of thing, so he certainly looked coached. He looked sincere. He looked like he wanted to work with the senators. But he also held his position. If there were issues about will you support a certain type of legislation, where obviously Facebook doesn't really want to support it, he said 'well I agree with the general principle and certainly our team can work with your people,' but when they tried to corner him about ' will you support certain legislation' he wouldn't do it."

"I think he went a long ways toward giving the kind of assurance that Facebook certainly wants to come out of this kind of hearing. I don't think he was nicked too badly. I think there were a couple questions around Cambridge Analytica where he sounded more ignorant, didn't have facts on his fingertips in the way that maybe he should have. But by and large I think at Facebook headquarters they're going to say, certainly at the end of today there still more hearings, but - mission accomplished."
