The board of the U.S. Capitol police union said it will move forward with plans to hold a no-confidence vote for the force's top leaders, including acting Chief Yogananda Pittman.
The vote will be held by week's end, a little more than a month after the Jan. 6 insurrection that left several people dead, including a Capitol police officer.
The Capitol's top three security officials, including the former police chief, Steven Sund, resigned in the days following the attack.
The union board said in a statement there was no alternative to the no-confidence motion, and systemic failures seen during the Capitol siege cannot be addressed without new leadership.
"The Board has taken this unprecedented step after reviewing senior leadership's handling of the January 6th insurrection at the Capitol that led to six deaths, and to injuries of approximately 140 Capitol and Metropolitan Police officers," the union said in a statement on Tuesday.
The vote will target Pittman, Assistant Chief Chad Thomas, acting Assistant Chief Sean Gallagher and several deputy chiefs, the union said.
