Rep. Seth Moulton, a Democratic congressman from Massachusetts, says he will boycott a moment of silence in honor of the victims of Sunday's gruesome mass shooting in Las Vegas.

Moulton, an Iraq War veteran and potential contender for the 2020 Democratic presidential nomination, tweeted Monday that he would "NOT be joining my colleagues in a moment of silence on the House floor that just becomes an excuse for inaction." He likewise did not partake in a moment of silence after the June 2016 mass shooting at the Pulse Nightclub in Orlando.

At the time, the Pulse Nightclub attack was the deadliest mass shooting in American history, but that record was surpassed on Sunday after Stephen Paddock killed at least 58 people at an outdoor concert in Las Vegas. In the aftermath of the shooting, numerous Democratic lawmakers called for stricter gun control laws, although the GOP-controlled Congress is unlikely to pass any new legislation regulating firearms.

Rep. Katherine Clark, another Massachusetts Democrat, will join Moulton in protesting the moment of silence, according to the Boston Herald. After the Pulse Nightclub shooting, Connecticut Democratic Rep. Jim Himes was the first Congressman to announce that he would not partake in a moment of silence for the victims.

"I just thought at some point, [a moment of silence] is perfectly emblematic of Congress' complete negligence on doing a bunch of things that we should do to try to reduce the bloody mayhem that happens in this country as a result of it being awash in guns," Himes told NPR at the time.
