Attorney General William Barr was reviewing the special counsel's confidential report on the Russia investigation Saturday to determine what should be made public after a nearly two-year probe that cast a dark shadow over Donald Trump's presidency.

Associated Press reporter Eric Tucker says that Barr will provide lawmakers and the public with a summary of principal findings as soon as this weekend.

The Attorney General  Barr will not be providing Congress with special counsel Robert Mueller's findings on Saturday.

That's according to a senior Justice Department official. The official spoke on condition of anonymity because the person wasn't authorized to publicly discuss the review process.

Mueller has concluded his investigation of Russian election interference and possible coordination with Donald Trump's campaign.

Barr is reviewing Mueller's confidential report and has said he expects to provide Congress with the "principal conclusions" this weekend.

And so to the extent that, that that has occurred that's a degree of relief for them. But I think everybody still waiting to see exactly what the report indicates about the Trump campaign and in the Trump administration. And so it's a little bit of a holding pattern. But the president who has spent the last basically two years attempting to undermine or sow doubt in the credibility an investigation has been noticeably quiet over the last 24 hours with no tweets about it and no public statements about it."

"The special counsel has indicated that he has not recommended any additional charges or indictments.

However, it's important to note that there are all sorts of other investigations going on that originated as referrals from the special counsel that he began investigating and recognized fell without outside of his mandate. And so he referred those back to the Justice Department which then sent them to individual offices of the Justice Department including in New York City and in Virginia."

A legal scholar says that the the battle between the Democrat-led House and President Donald Trump over special counsel Robert Mueller's report could lead to a constitutional crisis.

Victoria Nourse, a professor at Georgetown Law University, views the Trump administration as "the most combative" since former President Richard Nixon.

Nourse, who has served both Republicans and Democrats as a legal counsel, says that the current battle between Trump and House Republicans could end up in court.

While she believes that there is legal precedent that defends Congress' ability to request documents, Trump could ultimately decide not to comply with any judicial ruling.

"My biggest fear is that if it were to go to court and the court were to affirm Congress' authority that the president would simply refuse," Nurse said, referring to potential contempt proceedings against Attorney General Bill Barr and subpoenas House Democrats have threatened to issue over a number of investigations.  

"That would be a true constitutional crisis because in fact you would have one branch saying to the other branch, the courts, 'I'm not going to pay attention to you,' in which case there is no way to resolve that. The only way to resolve it would be in fact impeachment under the Constitution and that's a very extreme remedy."

House Judiciary Committee Chairman Jerrold Nadler has scheduled a Wednesday vote to hold Attorney General William Barr in contempt of Congress. Nadler is proposing to hold Barr in contempt after the Justice Department declined to provide the committee with a full, unredacted version of special counsel Mueller's report on Trump and Russia. The committee had given Barr until 9 a.m. Monday to comply.

Republicans have sharply criticized Democrats as they have battled Trump's administration over the Mueller report, subpoenaed multiple administration witnesses and made efforts to gain access to Trump's personal and business financial records. Trump has said he will fight "all the subpoenas."

"I think this White House has been the most combative since Nixon. And the reason I say this I was a baby lawyer during the Reagan administration and I was working on Iran-Contra. Reagan had his own investigation. He worked with Congress. There was a joint House and Senate committee investigation. George W. Bush worked with Congress on various matters. I don't think that this president is following the existing precedents. The last president I know who actually pursued the claim that he would not respond, his senior officials would not respond to House subpoenas was Nixon."

"This particular stance about refusing to honor subpoenas is very aggressive. Typically, these things happen every day up and down Pennsylvania Avenue. They're negotiated. Why? People don't want the American public to think that they are stonewalling, that they're not doing the business of the people."

6. SOUNDBITE: (English) Victoria Nourse, Georgetown Law Professor:

"The weight is in favor of Congress's investigatory authority. Now, his (President Donald Trump) argument will be, 'well they don't need it anymore because we have the Mueller report,' but his judgment is not the final judgment. We know that from United States versus Nixon. The Nixon case says the president cannot decide on his own. The court is the final arbiter of whether Congress needs this information or its within its congressional constitutional authority. So, I don't see any legitimate ground for the executive to be pushing back against Mueller testimony."

They will be scorned by clients and, therefore, they will not be seen as appropriate partners in law firms. This is a far -- or he may even be disbarred. These are much more consequential I think to significant, powerful lawyers than whatever fine or jail time might be involved."
