Democratic presidential candidate Kamala Harris is demanding to haul Attorney General Bill Barr in front of Congress to testify about the details of the Mueller report.

Americans deserve to know the truth now that the Mueller report is complete. The report must be released immediately and AG Barr must publicly testify under oath about the investigation's findings. We need total transparency here. — Kamala Harris (@KamalaHarris) March 22, 2019

Senator Cory Booker, who is also running for president, is also piling on.

This report should be made public immediately. https://t.co/Q2JCExqYaA — Cory Booker (@CoryBooker) March 22, 2019

The Trump Administration shouldn’t get to lock up Robert Mueller’s report and throw away the key. Taxpayers funded this investigation, and we deserve to know the outcome. Let me know if you agree: https://t.co/nYgagcL429 — Cory Booker (@CoryBooker) March 22, 2019

They're also using the situation to fundraise and farm emails.

Robert Mueller’s finished his report. He’s delivered it to Attorney General William Barr. The American people deserve the full report. Sign our petition to make the Mueller report public—immediately. https://t.co/kxhNh7GBWk — Elizabeth Warren (@ewarren) March 22, 2019

Barr sent a letter to Senate Judiciary Chairman Lindsey Graham, Ranking Member Dianne Feinstein, in addition to House Judiciary Chairman Jerry Nadler and Ranking Member Doug Collins late afternoon. He plans to brief them on the report over the weekend.

"I am reviewing the report and anticipate that I may be in a position to advise you of the Special Counsel's principal conclusions as soon as this weekend," Barr wrote. "Separately, I intend to consult with Deputy Attorney General Rosenstein and Special Counsel Mueller to determine what other information from the report can be release to Congress and the public consistent with the law, including the Special Counsel regulations, and the Department's long-standing practices and policies. I remain committed to as much transparency as possible, and will keep you informed as to the status of my review."

During his confirmation hearings in January, Barr repeatedly pledged to be as transparent as possible regarding the release of the Mueller report.
