House Speaker Nancy Pelosi said she doesn’t trust Attorney General William Barr and suggested his statement that he believes President Donald Trump’s campaign was spied on undermines Barr’s independence as the nation’s top law enforcement officer.

The California Democrat told The Associated Press she was “very concerned” about Barr’s handling of special counsel Robert Mueller’s Trump-Russia investigation report and accused Barr doing Trump’s political bidding.

“He is not the attorney general of Donald Trump. He is the attorney general of the United States,” Pelosi told AP. “I don’t trust Barr, I trust Mueller.”

Pressure is mounting on the attorney general in the days before his release of a version of Mueller’s nearly 400-page report, and Pelosi amplified the demands from Capitol Hill to see the full document. Barr said Wednesday he expects to release a redacted version within a week. Pelosi said it’s only a “matter of time” before the full report is made public.
