Virginia Sen. Mark Warner called for Attorney General William Barr’s resignation on Wednesday, saying Barr is “unfit for office” after the attorney general reportedly ordered peaceful protesters to be cleared from near the White House earlier this week.

Warner’s comments also come amid criticism over police tactics used to clear out the protesters ahead of President Donald Trump’s walk across Lafayette Square and the President’s subsequent photo-op in front of St. John’s Episcopal Church on Monday.

In a campaign email with the subject line “Barr Should Resign,” the Democrat cited reporting on the incident and the Justice Department’s decision to drop the criminal case against former national security adviser Michael Flynn.

“One thing is clear: Barr is unfit for office. He is acting as Donald Trump’s personal lawyer instead of fulfilling his duty to act in the public’s best interest,” Warner wrote.
