Update 7:15 p.m.: What we learned from Barr’s testimony

Original post:

Attorney General William Barr has faced congressional grilling before, but his testimony before lawmakers this week is likely the most important of his career, and may be critical to the future of the president who appointed him.

This is the first time Barr will testify before Congress since he released a redacted version of special counsel Robert Mueller’s report, which detailed Russian attempts to influence the 2016 election and attempts by President Donald Trump to block or limit the investigation, though Mueller did not reach a conclusion on whether the president obstructed the probe. It is also Barr’s first appearance as attorney general before a judiciary committee, which has direct oversight over the Department of Justice. (His previous testimony as attorney general this year was to appropriations committees.)

The hearings this week come amid reports that Mueller raised significant concerns about how Barr had summarized the conclusions from his investigation.

It is not yet clear if Barr will testify before the House Judiciary Committee as scheduled Thursday; Democrats say he objects to that committee’s plan for staff attorneys to question him.

But Barr’s appearance Wednesday before the Senate Judiciary Committee is compelling on its own. Here are five things to watch.
