Trump's defense attorney is a no-show for Thursday's House Judiciary Committee hearing.
Capitol Hill has been buzzing about the unlikely prospect of using a jail that some say exists somewhere in the Capitol and that was used in the past to detain those in contempt of Congress.
He said presidents with "too much power" can easily make decisions that undermine government operations in everyday lives.
Democrats need to decide what to do now. In all, it is likely to prompt a vote on holding Barr in contempt and possibly the issuance of subpoenas, bringing House Democrats and the Trump administration closer to a prolonged battle in court.
The battle for members of Congress to gain full access to the un-redacted Mueller report has been ongoing since Barr released the redacted report to the public on April 18.
On Friday, Nadler made good on that promise. The letter zeroes in on a line found in Volume II of the report in which Mueller's teams said the evidence prevented them from "conclusively determining no criminal conduct occurred".
"It can not go unremarked that, in refusing to comply with congressional oversight requests, the department has repeatedly asserted that Congress's requests do not serve "legitimate" purposes", Nadler wrote. "This is not the department's judgment to make".
"Mueller Time" has come and gone and with Election 2020 looming, it may be time for Democrats to move on and focus on other matters.
Democrats say they are considering all options.
"William Barr has forfeited his right to hold the office of the Attorney General", Steyer, a longtime environmentalist and Democratic donor, said in a statement to The Washington Post.
But if the US attorney declines to prosecute, Democrats have other methods to force compliance with witnesses, like hefty fines for witnesses who fail to appear. "As you probably know, in the Articles of Impeachment for President Nixon, Article 3 was that he ignored the subpoenas of Congress, that he did not honor the subpoenas of Congress".
The top House Judiciary Committee Democrat has delivered a final warning to Attorney General William Barr to comply with a subpoena for the full Mueller report and its underlying evidence or else face contempt of Congress proceedings.
"I'm going to write a letter to Mr. Mueller and I'm going to ask him, 'Is there anything you said about that conversation he disagrees with?' And if there is, he can come and tell us", Graham said at Wednesday's hearing.
Trump had a famously fraught relationship with his first attorney general, former Republican Sen. "That's a crime", she said.
Within minutes of Ms Pelosi's comments, Justice Department spokeswoman Kerri Kupec called her words "reckless, irresponsible and false".
Not every reaction has been as serious.
That's not hyperbole. This is a thing that Rep. Cohen repeated several times. Harris' letter describes Barr as "unable or unwilling to answer the question".
"I can understand why they're making that characterization for political purposes, but it has no basis in fact", said Flanigan, who is now the chief legal officer for Cancer Treatment Centers of America.
"He was very clear with me that he was not suggesting that we had misrepresented his report", Mr Barr said. "I only wish when she was secretary of state, she would have taken it on instead of allowing it to get where it is today and turning a willful blind eye to that".
Nadler has invited Mueller to testify on May 15.
Meanwhile, Trump told reporters at the White House that he will decide in the coming days whether he will allow former White House lawyer Don McGahn to testify before USA lawmakers or whether he will invoke executive privilege to block his testimony. "Congress shouldn't be looking anymore".
This is the same Napolitano who told us Trump committed a felony and will be indicted over what is, at worst, a campaign finance violation that might result in a fine. That could potentially lead to fines or imprisonment for the top United States law-enforcement official.
