A retired New York City police officer was found guilty on Monday of attacking a Washington, DC, cop during an attack on the Capitol in January of 2021.

A jury found him guilty of disorderly conduct with a dangerous weapon and being on restricted Capitol grounds. A former New York City cop, who later worked for the mayor, faces a potential years-long prison sentence.

The jury returned the guilty verdict after just hours of deliberations Monday, following a week-long trial that featured testimony from the Washington, DC, police officer who was attacked. The video footage from January 6 shows a confrontation between Officer Noah Rathbun and Webster at the Capitol bike rack, and then Webster slamming a flag pole into the metal barrier between them.

The video footage showed that the metal barrier was broken by Webster and that he tackled Rathbun to the ground. On the witness stand, Rathbun recounted feeling overwhelmed by the sheer size of the crowd on January 6 and remembered feeling choked by his helmet's chin strap as he tried to help the officer.

He argued that he was acting in self-defense when he swung his flag pole. On Thursday, he testified that he was hit by afreight train along a metal bike rack.

James Monroe showed video footage that appeared to show Rathbun making contact with the head of the police officer protecting the Capitol. As he tried to gesture for him to back up from the metal barrier, he made contact with him and with an open hand.
