House Democrats don't expect to hold another sit-in on the House floor to protest the absence of gun control legislation, in part because they expect Republicans to enforce tighter discipline against those kinds of activities.

Democrats last year disrupted the work of the House by holding a day-long sit-in that stopped lawmakers from getting any work done. That tactic was used to protest the lack of a gun bill in the wake of the Pulse nightclub shooting, which was the worst mass shooting in U.S. history at the time.

But one Democratic leader told the Washington Examiner that there are no plans to do that again in the wake of the Las Vegas shooting, which eclipsed the Pulse shooting in Orlando and became the deadliest mass shooting for the U.S.

"We have to use different tools and different tactics for the right situations," said Rep. Linda Sanchez, D-Calif., the House Democratic caucus' vice chair. "I just don't think it's going to be as impactful as it was the first time."

"That didn't come up in caucus meeting yesterday," she added on Wednesday. "Clearly, people want to jump to that right away, and I think the last sit-in was very effective in galvanizing, sort of, Americans around the issue. People really embrace that. People around the country really embrace that."

Sanchez acknowledged that a factor in the decision is the likelihood of Republicans enforcing discipline against demonstrations that violate House rules. Republicans complained in 2016 that Democrats were shooting live video from the House floor once the GOP turned off the cameras, and while Democrats got a pass then, they would likely face consequences this time around.

House Speaker Paul Ryan, R-Wis., put new rules into effect at the start of the current Congress that ban members from taking photos and videos on the House floor. Anyone who takes a photo on the floor faces a $500 fine for the first offense and a $2,500 fine for a second offense.

"With that, there have been subsequent tougher rules and ethics complaints, and so the speaker has made clear that he will be enforcing all of those rules," Sanchez said.

"There are still discussions within the caucus about what we might want to do. Obviously, before the caucus moves forward on any of that they'll have to reach a consensus," Sanchez added.

At the moment, Democrats are not overly optimistic any measures can get through to President Trump's desk, protests or not. There is an openness among lawmakers, however, to a bill banning "bump stocks" — devices that enable a shooter to rapidly fire bullets and mimic automatic weapon fire.

The Las Vegas shooter, Stephen Paddock, seemed to use this equipment for the shooting, which left more than 500 injured.

That could be a way forward for a bill to move, as Sen. John Cornyn, R-Texas, said the availability of bump stocks is "certainly something that's got my attention" and is an issue worth having a hearing about to learn more. However, Democratic lawmakers are not holding their breath, and some say much more needs to be done.

"We're going to hear an earful when we go home this weekend," said Rep. Rick Larsen, D-Wash. "There's no one action Congress can take to prevent what happened in Las Vegas ... The issue is we can't be making gun law policy based on the last mass shooting that occurred because they all are unique."

At the same time, Larsen agreed that legislation dealing with bump stocks could be something that lawmakers learn more about and act on.

"I had not heard of a bump stock before," Larsen admitted. "Now that I know about a bump stock, the ability to convert a non-automatic weapon into an automatic weapon for the sake of $200 seems to me something we should move forward on and do."
