William Barr Testimony Live Stream: AG Appears at Senate Hearing After Reports of Robert Mueller's Letter

Attorney General William Barr will face lawmakers for the first time since releasing a redacted version of special counsel Robert Mueller's final report on the Russia investigation in what is expected to be a dramatic showdown on Wednesday.

Barr will testify before the Senate Judiciary Committee starting at 10 a.m. EDT. The hearing can be watched via a live stream below, courtesy of NBC News.

Barr's appearance on Capitol Hill immediately follows the revelation that Mueller wrote a letter to the attorney general in late March objecting to the way Barr presented the key findings of the two-year probe into Russian interference in the 2016 election, according to reports published on Tuesday by The New York Times and The Washington Post.

The Justice Department told The Times that Mueller had expressed frustration with Barr's initial four-page summary of the report in which the attorney general said the special counsel did not find that Trump or his associates had conspired with Russia to influence the 2016 presidential election, and did not reach a conclusion on whether Trump had attempted to obstruct justice. Barr, acting independently, said he found the evidence insufficient to charge Trump with obstruction of justice—a decision that stunned legal experts and former federal prosecutors.

In light of reports by The Times and The Post, top Democrats immediately rebuked the attorney general and called for an official investigation into his handling of the special counsel's report.

“Attorney General Barr's actions raise significant questions about his decision not to recuse himself from overseeing the Special Counsel's investigation, whether his actions with respect to the release of the report complied with Department of Justice policies and practices, and whether he has demonstrated sufficient impartiality to continue overseeing the fourteen criminal matters related to the Special Counsel's investigation,” a dozen Senate Democrats wrote in a letter to the Justice Department's Office of the Inspector General.

House Judiciary Committee Chairman Jerry Nadler has also demanded that the letter Mueller sent to Barr be handed over to Congress. He has also called for the special counsel to testify before lawmakers.

Barr's four-page summary of the Mueller report led the president to declare that he had been fully exonerated.

But the release of the redacted 448-page report gave a more detailed view of Trump's conduct, citing at least 12 instances in which he might have obstructed justice throughout the 22-month investigation. The report also highlighted Mueller's reasoning behind not charging the president and why he might have left that up to Congress.

Despite facing heavy scrutiny, Barr has continued to defend himself and his handling of the special counsel's investigation and is expected to do the same during his testimony on Wednesday, according to Barr's prepared opening statement.

“With the completion of the Special Counsel's investigation and the resulting prosecutorial decisions, the Department's work on this matter is at its end aside from completing the cases that have been referred to other offices,” Barr is expected to say on Wednesday. “From here on, the exercise of responding and reacting to the report is a matter for the American people and the political process.”
