In the wake of the deadly assault on the U.S. Capitol last month, six Capitol Police officers have been suspended with pay and another 29 officers are under investigation, a spokesman for the department said, according to reports.

"Our Office of Professional Responsibility is investigating the actions of 35 police officers from that day," spokesman John Stolnis told FOX 5 of Washington, D.C. "Acting Chief Yogananda Pittman has directed that any member of her department whose behavior is not in keeping with the Department’s Rules of Conduct will face appropriate discipline."

Stolnis didn’t specify what allegations led to the suspensions or why the officers were being investigated.

A few officers have been accused of allowing the rioters to breach the Capitol with no pushback - despite the many outnumbered officers who struggled to keep them out - and at least two rioters have told the FBI an officer said to them, "This is your house now" when rioters smashed their way in the building, FOX 5 reported.
