Several Democratic chairmen pressed the administration for witness testimony and documents from several government entities, from the Defense Department to the Secret Service to the Justice Department.

House Homeland Security Committee Chairman Bennie G. Thompson (D-Miss.) described himself as “stunned, disturbed, and furious” after law enforcement forcibly cleared the streets Monday night moments before Trump took a walk across Lafayette Square to pose with a Bible in front of St. John’s Episcopal Church.

Thompson demanded in a letter to Secret Service Director James M. Murray that he provide a briefing on his organization’s role in “planning, coordinating, and executing these actions.”

“It is shameful that the President used the power of the federal government to attack Americans exercising their constitutional right to protest just so he could stage a photo opportunity,” Thompson wrote.
