Attorney General William Barr took a sarcastic jab at House Speaker Nancy Pelosi (D-California) Wednesday about his potential arrest during an event in Washington, D.C. held to honor fallen law enforcement officers.

“Madame Speaker, did you bring your handcuffs?” quipped Barr.

Pelosi reportedly responded by smiling and noting that the House sergeant-at-arms was present for any necessary arrests. Barr simply laughed and left the ceremony.

Tensions between the White House and congressional Democrats are high, especially after the House Judiciary Committee voted earlier this month to hold Barr in contempt for his lack of compliance in the fallout of the release of special counsel Robert Mueller‘s report on his investigation into Russian meddling in the 2016 election.

The Trump administration sent the House panel a 12-page letter on Wednesday that essentially stated its refusal to hand over documents with information relevant to a congressional investigation into Trump’s presidency. The letter claimed Democrats had no “legitimate” purpose in continuing their probes.

The full House of Representatives is expected to hold a vote on whether to hold Barr in contempt in the coming weeks.

“Let me just say that we do have a jail down in the basement of the Capitol,” Pelosi recently said during a Washington Post interview. “But if we were arresting all of the people in the administration, we would have an overcrowded jail situation, and I’m not for that.”
