“Attorney General 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," Pelosi and Schumer wrote in a statement.

"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," they continued.

Democrats' ire over the report's rollout has grown in recent weeks.

They have blasted the president's top law enforcement official for releasing a four-page letter describing the principal findings of the probe, in which Barr said that Mueller determined there was no coordination between the Trump campaign and Russia.
