Barr to Appear Before Congress as Lawmakers Await the Mueller Report

• Attorney General William P. Barr is scheduled to testify before Congress on Tuesday and Wednesday to discuss the Justice Department budget, a usually staid affair that could become dramatic if lawmakers grill him about the Mueller report.

• Members of the House and Senate Appropriations Committees may also question him about the Justice Department’s decision to stop defending the Affordable Care Act in court.

• Mr. Barr is likely to try to keep the conversation focused on the department’s proposed $29.2 billion budget, which includes money for 100 new immigration judges as President Trump hardens his stance on immigration along the southwestern border.

Appropriations hearings are ostensibly about asking cabinet officials to justify their budgets, but Mr. Barr has already come under fire from Democrats for his handling of the highly anticipated special counsel’s report and will face a Democrat-led House Appropriations Committee on Tuesday.

Democrats have criticized Mr. Barr’s decision to share Mr. Mueller’s top-line findings in a four-page letter that quoted sparingly from the report itself and his declaration that Mr. Trump had not committed an obstruction-of-justice offense after Mr. Mueller declined to make a prosecutorial judgment. They renewed their complaints after The New York Times revealed last week that some of Mr. Mueller’s investigators have complained that Mr. Barr failed to fully represent their findings and that they were more damaging for the president than the attorney general indicated.

“The American people have been left with many unanswered questions; serious concerns about the process by which you formulated your letter; and uncertainty about when we can expect to see the full report,” Representative José E. Serrano, Democrat of New York and the head of the appropriations subcommittee that covers the Justice Department, planned to say in Tuesday’s hearing, according to prepared remarks.

Representative Nita M. Lowey, Democrat of New York and the chairwoman of the House Appropriations Committee, called Mr. Barr’s handling of the Mueller report “unacceptable” in her prepared remarks and said that his letter seemed to “cherry pick from the report to draw the most favorable conclusion possible for the president.”

Mr. Barr has insisted that he is being as transparent as he can be and that he wrote the letter to share the main investigative findings with the public as soon as possible while he and other law enforcement officials review the full report. He has vowed to give copies to Congress by mid-April, after lawyers from the special counsel’s office and the Justice Department have had time to redact classified materials, secret grand jury testimony and information related to open investigations.

Mr. Barr was expected to avoid giving any answers that could generate headlines, especially given that his pick for the No. 2 spot at the Justice Department, Jeffrey A. Rosen, goes before senators for his confirmation hearing on Wednesday. Mr. Barr is likely to decline to answer questions about the Mueller report and instead stick with his budget priorities, which include more money to combat the opioid epidemic, crack down on violent crime and protect the country against national security threats.

Mr. Barr is requesting an additional $72.1 million for immigration enforcement — an amount that would fund 100 new immigration judges — at a time when Mr. Trump has hardened his stance against illegal immigration and asylum seekers. Over the past two days, he has purged top immigration and security leaders to accelerate that goal.

Lawmakers have demanded that the White House provide answers.

While Mr. Barr said in his prepared remarks that the additional judges will “provide some relief from a critical backlog in the immigration courts,” he also said that the continuing influx of cases along the southwestern border “constrains our ability to manage the backlog of cases, and other reforms are necessary.”

The Justice Department oversees the nation’s immigration judges, who are separate from the judicial branch.
