"Attorney General [William] Barr's regrettably partisan handling of the Mueller report, including his slanted March 24th summary letter, his irresponsible testimony before Congress last week, and his indefensible plan to spin the report in a press conference later this morning – hours before he allows the public or Congress to see it – have resulted in a crisis of confidence in his independence and impartiality," the Democratic leaders said in the statement Thursday morning.

“We believe the only way to begin restoring public trust in the handling of the Special Counsel’s investigation is for Special Counsel Mueller himself to provide public testimony in the House and Senate as soon as possible. The American people deserve to hear the truth.”

The Justice Department said the redacted report, which details Mueller's findings following his investigation into possible Russian interference in the 2016 presidential election, will be released sometime Thursday morning. Barr, who wrote a controversial summary of the report last month, plans to hold a news conference at 9:30 a.m. EDT ahead of the report's release.
