Attorney General Jeff Sessions was interviewed for hours last week in special counsel Robert Mueller's Russia investigation, the Justice Department confirmed Tuesday. He's the highest-ranking Trump administration official and first Cabinet member known to have submitted to questioning.

The interview came as Mueller investigates whether President Donald Trump's actions in office, including the firing of FBI Director James Comey, constitute efforts to obstruct the FBI probe into contacts between his 2016 campaign and Russia. Trump's own lawyers are discussing the prospect of an interview with the president himself, and White House officials state publicly that they anticipate a resolution soon to the investigation.

The questioning of the country's chief law enforcement officer is a reflection of investigators' continued interest in whether the president took steps to improperly obstruct justice. That question has been at the heart of the investigation for months as agents and prosecutors have questioned multiple current and former White House officials.

Sessions himself is seen as a potentially important witness given his direct involvement in the May 9 firing of Comey. The White House initially said the termination was done on the recommendation of the Justice Department and cited a memo from Deputy Attorney General Rod Rosenstein that faulted Comey for his handling of the Hillary Clinton email server investigation as justification.

But Trump said later that he was thinking of "this Russia thing" when he fired Comey, and he had decided to make the move even before the Justice Department's recommendations.

Sessions was one of Trump's earliest and most loyal allies, the first senator to endorse him during the presidential campaign. They shared an ambitious law-and-order agenda that focuses on hawkish immigration policies and tough-on-crime strategies that engendered affection from many conservatives.

He has continued to push Trump's agenda on everything from gangs and the opioid crisis to religious freedom, giving the president credit every step of the way.

But his decision to step aside from the Russia investigation has strained their bond, and the two men now rarely speak directly. Trump saw the recusal as weak and disloyal, believing his attorney general should be doing more to protect him

Over the past several months Mueller investigators have spoken with other key people close to the president, including White House Counsel Don McGahn, former chief of staff Reince Priebus and Trump's son-in-law, Jared Kushner.

Mueller has conveyed interest in speaking with the president, and White House attorney Ty Cobb said that is "under active discussion" with Trump's individual lawyers. He said last week on a CBS News' political podcast, "The Takeout," that he expected the investigation to be wrapped up within weeks.

Sessions recused himself from the Russia investigation in early March after acknowledging that he had had two previously undisclosed encounters with the Russian ambassador during Trump's 2016 presidential campaign. He said at the time that it would be improper for him to oversee a probe into a campaign for which he was a vocal and prominent supporter.

Since then, Trump has lashed out repeatedly on Twitter at Sessions and the Justice Department.

People familiar with the matter have told The Associated Press that McGahn had contacted Sessions to urge him to retain control of the investigation. McGahn was acting at the behest of the president, according to one of those people, who spoke only on condition of anonymity because the person was not authorized to speak publicly by name.

Rosenstein appointed Mueller, a former FBI director, to take over the Russia investigation one week after Comey was fired. He oversees the work of Mueller's investigators, but he told the AP in an interview last June that he, too, would recuse himself if his actions ever became relevant to the probe.

Sessions' attorney, Chuck Cooper, declined to comment, as did the White House.

Four people have so far been charged in the Mueller investigation, including former White House National Security Adviser Michael Flynn and former Trump campaign chairman Paul Manafort. Flynn and George Papadopoulos, a former campaign foreign policy adviser, have pleaded guilty to lying to the FBI.

Sessions' interview with the Mueller team was first reported by The New York Times.

"White House lawyer Ty Cobb has been on record as saying he anticipates the investigation will resolve soon. He's put a time frame of four to six weeks. We're not sure if that's actually going to happen. It's sort of hard to predict for anyone when these investigations will end."

A Dutch attorney who lied to federal agents investigating former Trump campaign chairman Paul Manafort was sentenced April 3rd to 30 days in prison in the first punishment handed down in special counsel's Russia investigation. He was also ordered to pay a $20,000 fine.

Alex van der Zwaan's sentence could set a guidepost for what other defendants charged with lying in special counsel Robert Mueller's investigation may receive when their cases are resolved. Among them are a former White House national security adviser and a Trump campaign foreign policy aide.

Van der Zwaan had faced zero to six months in prison under federal sentencing guidelines, and his attorneys had pushed for him to pay a fine and leave the country. But U.S. District Judge Amy Berman Jackson, citing the need to deter others from lying in an investigation of international importance, said incarceration was necessary.

The criminal case against van der Zwaan is not directly related to Russian election interference, the main focus of Mueller's probe. But it has revealed new details about the government's case against Manafort as well as previously undisclosed connections between senior Trump campaign aides, including Rick Gates, and Russia. The allegations have also opened a window into the intersecting universes of international law, foreign consulting work and politics.

Van der Zwaan admitted in February to lying to federal agents about his contacts with Gates and a person prosecutors have since revealed has been assessed to have ties to Russian intelligence. Though prosecutors did not take a position on whether he should be locked up, they stressed that he had lied "repeatedly" to investigators.

Van der Zwaan's attorneys argued that he had suffered enough already, saying his life had already been destroyed by his "terrible decision" to lie to federal authorities.

The attorneys also pushed Jackson to allow van der Zwaan to return to London as soon as possible where he lives with his wife, who is pregnant with their first child.

James Comey blasts US President Donald Trump as unethical and "untethered to truth" and his leadership of the country as "transactional, ego driven and about personal loyalty," according to a forthcoming book from the former FBI director.

Comey reveals new details about his interactions with Trump and his decision-making in handling the Hillary Clinton email investigation.

He casts Trump as a mafia boss-like figure who sought to blur the line between law enforcement and politics and tried to pressure him regarding the investigation into Russian election interference.

The book adheres closely to Comey's public testimony and written statements about his interactions with the president during the early days of the administration and his growing concerns about the president's integrity. But it also includes surprisingly personal jabs at Trump that appear likely to irritate the notoriously thin-skinned president.

The 6-foot, 8-inch tall Comey describes Trump as shorter than he expected with a "too long" tie and "bright white half-moons" under his eyes that Comey suggests came from tanning goggles. He also says made a conscious effort to check the president's hand size, saying it was "smaller than mine, but did not seem unusually so."

The book, "A Higher Loyalty," is set to be released next week. The Associated Press purchased a copy this week.

Trump fired Comey in May 2017, setting off a scramble at the Justice Department that led to the appointment of Robert Mueller as special counsel overseeing the Russia investigation.

Comey writes that he regrets his approach and some of the wording he used in his July 2016 press conference in which he announced the decision not to prosecute Clinton.

But he says he believes he did the right thing by going before the cameras and making the statement, noting that the Justice Department had done it in other high profiles cases before.

Every person on the investigative team, Comey writes, found there was no prosecutable case against Clinton and that the FBI didn't catch her in a lie.

He also reveals for the first time that the U.S. government had unverified classified information that he believes could have been used to cast doubt on Attorney General Loretta Lynch's independence in the Clinton probe.

While Comey does not outline the details of the information - and says he didn't see indications of Lynch inappropriately influencing the investigation - he says it worried him that the material could be used to attack the integrity of the probe and the FBI's independence.

Former Trump campaign chairman Paul Manafort arrived at a US federal courthouse in Washington, on April 19th as he seeks to challenge special counsel Robert Mueller's authority by arguing that Mueller overstepped his authority. Manafort is expected to ask a judge to throw out charges brought against him.

Gina Haspel - who's been nominated to be CIA director - says she wouldn't put in place any presidential order that she thought was immoral, even if it was technically legal.

A Senate committee is holding a hearing on Haspel's nomination, and Virginia Democrat Mark Warner asked whether she'd carry out any order from President Donald Trump that she found morally objectionable.

Haspel said she wouldn't.

My moral compass is strong," Haspel said.

"I would not allow CIA to undertake activity that I thought was immoral, even if it was technically legal. I would absolutely not permit it."

Haspel said the CIA must undertake activities consistent with American values.

U.S. President Donald Trump says he "unleashed an economic miracle" with his tax cuts in 2017.

Trump spoke on June 29th at a White House event marking the six-month anniversary of the $1.5 trillion tax cuts.

The cuts are taking effect in the ninth year of an economic expansion that began under former President Barack Obama.

Trump called the cuts the "biggest" in history. The overhaul ranks behind Ronald Reagan's in the early 1980s and post-World War II tax cuts.

The law provides generous tax cuts for corporations and the wealthiest Americans, and more modest reductions for middle- and low-income individuals and families.

Trump has been enjoying a good week, with two favorable Supreme Court rulings and Justice Anthony Kennedy's plans to retire from the Supreme Court.

Trump says US tax cuts "unleashed an economic miracle"

8. SOUNDBITE (English) Donald Trump, US President:

"Thank you very much everybody. The economy is indeed doing well. (Cheers.) Six months ago we unleashed an economic miracle by signing the biggest tax cuts and reforms, I have to add the word reform, very important word. But the tax cuts is what got us there and that is what is really doing it, the biggest tax cuts in American history.

Former Trump campaign chairman Paul Manafort agreed Friday to cooperate with the special counsel's Russia investigation as he pleaded guilty to federal charges and avoided a second trial that could have exposed him to even greater punishment.

The deal gives special counsel Robert Mueller a key cooperator who led the Trump election effort for a crucial stretch during the 2016 presidential campaign.

It is unclear what information Manafort is prepared to provide to investigators about President Donald Trump or that could aid Mueller's investigation into Russian interference in the 2016 presidential election. But the plea nonetheless makes Manafort the latest associate of Trump, a president known to place a premium on loyalty among subordinates, to admit guilt and cooperate with investigators in hopes of leniency.

AP Justice Department reporter Eric Tucker explains, "what's really significant about the cooperation is there is nothing that would stop Paul Manafort from describing to the special counsel acts and crimes and incidents that aren't what he pleaded guilty to."

"So if he has information that he is not admitting guilt to, he can still provide it to the government. He's still encouraged to provide it to the government. And that is information that of course could be about the campaign and could be about Donald Trump," Tucker adds.

The cooperation deal requires Manafort to provide whatever information the government asks of him, though it does not specify what if anything prosecutors hope to receive about Trump.

Given his direct involvement in the Trump campaign, including episodes being scrutinized by Mueller, Manafort could be positioned to provide key insight for investigators working to establish whether the campaign coordinated with Russia.

Manafort was among the participants, for instance, in a June 2016 Trump Tower meeting with Russians and the president's oldest son and son-in-law that was arranged so the campaign could receive derogatory information about Democrat Hillary Clinton. A grand jury used by Mueller has heard testimony about the meeting.

Friday's deal, to charges tied to Ukrainian political consulting work but unrelated to the campaign, was struck just days before Manafort was to have stood trial for a second time.

He was convicted last month of eight financial crimes in a separate trial in Virginia and faces seven to 10 years in prison in that case. The two conspiracy counts he pleaded guilty to on Friday carry up to five years in prison, though Manafort's sentence will ultimately depend on his cooperation.

In the past year, Mueller has secured pleas from a former national security adviser who lied to the FBI about discussing sanctions with a Russian ambassador, a campaign aide who broached the idea of a meeting with Russian President Vladimir Putin; and another aide who was indicted alongside Manafort but ultimately turned on him. The president's former personal lawyer has separately pleaded guilty in New York.

White House press secretary Sarah Sanders insisted that the Manafort case was unrelated to Trump.

"This had absolutely nothing to do with the president or his victorious 2016 presidential campaign. It is totally unrelated."
