In a video posted to Facebook Monday evening, California Rep. Ted Lieu said that he would not join his colleagues who were observing the moment of silence in the chambers of the House of Representatives.

“I can’t do this again; I’ve been to too many moments of silences,” Lieu said in the video. “In just my short period in Congress, three of the worst mass shootings in U.S. history have occurred. I will not be silent.”

“I urge us to pass reasonable gun safety legislation, including a universal background check law supported by 80 percent of Americans, a ban on assault rifles and a ban on bump stocks,” Lieu added.
