Within minutes of receiving notification that special counsel Robert Mueller had turned over his report on the Russia investigation, congressional Democrats were calling for the report to be fully released, including the underlying evidence. They have threatened subpoenas if it is not.

The demands are setting up a potential tug of war between congressional Democrats and President Donald Trump's administration that federal judges might eventually have to referee.

Six Democratic committee chairmen wrote in a letter to Attorney General William Barr on Friday that if Mueller has any reason to believe that Trump "has engaged in criminal or other serious misconduct," then the Justice Department should not conceal it.

"The president is not above the law and the need for public faith in our democratic institutions and the rule of law must be the priority," the chairmen wrote.

Reacting to the release, Democratic Congressman Ted Lieu, who serves on the Judiciary Committee, told the Associated Press that "the American people paid for this report," adding "both American people and Congress have a right to see the full report. "

Lieu said although the special counsel report focused on Russia, the findings could also be used in a wide array of Judicary Committee investigations.

It's unclear what Mueller has found related to the president, or if any of it would be damning. In his investigation of whether President Donald Trump's campaign coordinated with Russia to sway the 2016 election, Mueller has already brought charges against 34 people, including six aides and advisers to the president, and three companies.

Lawmakers say they need the underlying evidence - including interviews, documents and material turned over to the grand jury - because the Justice Department has maintained that a president cannot be indicted, and also that derogatory information cannot be released about people who have not been charged. So if the investigation did find evidence incriminating against Trump, they may not be able to release it, under their own guidelines.

The Democrats say that it could be tantamount to a cover-up if the department did not let Congress and the public know what they found.

"Today is a proud day for America. Despite many attempts by Donald Trump to block this investigation Robert Mueller and his team were able to complete it. The fact that Mueller and Deputy Attorney General Rod Rosenstein kept their jobs I think is a strong testament to the vitality and strength of our institutions. This was a Republican led investigation of a Republican president and it was allowed to continue. I think that says a lot about America."

"It's hard to know without knowing what's in the actual report. It's also important to understand that because the Department of Justice has taken the position that they won't indict a sitting president then the only other institution that can hold the press accountable is Congress. And we can't do that if we don't see the full report. So, that at every level when you look at it from separation of powers or the functions of both Congress and the special counsel in this case, the different functions we have to see the entire report."

"Special Counsel Mueller's investigation was largely centered on Russia. The House Judiciary Committee and other committees were interested in knowing did Donald Trump, his family, his associates commit any crime? Second, did they engage in any ethical misconduct, whether or not it rose to the level of a federal crime? And third how do we explain this to the American people to keep it from happening again?"

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."

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."
