Democrats, who largely criticized Barr’s appointment as attorney general, immediately questioned the conclusions he drew from Mueller’s report. They questioned why Barr decided the evidence gathered was not sufficient for obstruction charges.

“Special Counsel Mueller clearly and explicitly is not exonerating the President, and we must hear from AG Barr about his decision making and see all the underlying evidence for the American people to know all the facts,” Rep. Jerry Nadler, a New York Democrat and chairman of the House Judiciary Committee, said in a tweeted statement.

“There must be full transparency in what Special Counsel Mueller uncovered to not exonerate the President from wrongdoing. DOJ owes the public more than just a brief synopsis and decision not to go any further in their work,” he said in a second tweet.

Mueller submitted his report and ended the probe on Friday without further indictments. A senior law enforcement official told NBC News that are also no sealed indictments pending release.

The special counsel was tasked with investigating Russian interference in the 2016 presidential campaign, possible collusion between the Trump campaign and the Russian government as well as any other matters arising from the investigation.

Members of Congress have called on Barr to provide full transparency. In a rare bipartisan vote in an era of deep partisanship, the Democratic-controlled House of Representatives voted 420-0 in favor of a non-binding resolution demanding the public release of Mueller’s full report. The GOP-held Senate blocked the measure.

In a letter to Congress Friday, Barr said he is “committed to as much transparency as possible.”

Barr was appointed attorney general after Trump forced Jeff Sessions out of the job.

Trump had repeatedly criticized Sessions for recusing himself from the Russia investigation after the former Alabama senator failed to disclose during testimony to Congress contacts he had with the Russian ambassador in the runup to the 2016 presidential election.

Trump has repeatedly called the special counsel’s investigation a “witch hunt.” But Barr, a Trump appointee, said in his Friday letter that there were no instances in which the special counsel’s actions were “inappropriate or unwarranted.”

Trump has said it is Barr’s decision whether the full report will be released.
