The fight is only just beginning. Democrats were eager to impress that message upon a crowd that gathered outside the U.S. Capitol on Thursday afternoon after emerging from a sit-in on the House floor demanding action on gun control that lasted more than 24-hours.

“Don’t give up, don’t give in,” the Democratic congressman and civil-rights leader John Lewis said as onlookers waved rainbow-colored signs that read “Disarm Hate.” The crowd began to sing the civil-rights protest anthem “We Shall Overcome,” with lyrics slightly modified to suit moment: “We shall pass a bill someday.” A woman recording a video on her cellphone remarked aloud, “This is history, baby,” to no one in particular.

The sit-in was an unusual moment of protest inside the United States Congress. The willingness to make such a bold, publicity-ready move suggests the Democratic Party feels emboldened to demand action on gun control in the wake of a tragic mass shooting at an Orlando nightclub earlier this month. In the end, however, Democrats did not succeed in securing a vote on the gun-control measures they had hoped for in staging the protest.

Faced with that failure, Democrats insist this is only the beginning. “We’re going to continue to work,” Lewis said in a brief interview outside the Capitol. “Many people are supporting our efforts,” he said. “People all over America and around the world are supporting our efforts to do something about gun violence.”

The sit-in may also indicate that House Democrats are increasingly willing to make use of confrontational tactics to make their voices heard. “It’s not just about guns,” the Democratic congressman James Clyburn said in an interview. “This particular issue is about guns, but this is just the start … I wouldn’t get hung-up on sit-ins, but I would call it activism.”

House Minority Leader Nancy Pelosi seemed reluctant to declare that this will be the way Democrats try to get their message on future issues. “No, I think you have to just take it on a day-to-day basis,” she said at Thursday’s press conference. She called the sit-in a reflection of the “the complete insistence that we cannot go through another moment of silence without taking action” on gun violence.

The sit-in seemed to intensify the divide between Democrats and Republicans on guns. House Speaker Paul Ryan denounced the action as a “publicity stunt,” during an interview with CNN. “This is not about a solution to a problem,” he said. “This is about trying to get attention.” House Republicans expressed frustration over the Democrats’ action, describing the event as a political distraction and a way to obstruct the business of legislating.

In an interview, the Republican congressman Mark Meadows said that while it is “certainly within every member’s right to be able to articulate their concerns,” he disagreed with the tactics deployed by Democrats. As Yoni Appelbaum noted, “even having phones switched on, much less snapping photos, tweeting updates, or periscoping the proceedings, is a violation of the rules of the House”—all common sights during the sit-in.“I think it poses a very bad precedent and quite frankly other nations are watching what is happening,” Meadows said.

The Democrats’ agenda faced criticism from progressives as well. Democrats were agitating for a vote on measures to expand background checks for gun purchases and prevent suspected terrorists from buying the weapons. As The Intercept’s Zaid Jilani wrote, the “unusually bold and moving tactic was undercut by the fact that its chief goal is a political gimmick that would do little to stop gun violence, while expanding the use of a deeply flawed anti-terror watchlist.”

In spite of various criticisms, many House Democrats appeared defiant and energetic Thursday afternoon. “The American public has been crying out for help on this issue, for their families, for their kids, and we said ‘We hear you, we’re listening to you and, we’re going to do something about it,’” the Democratic congresswoman Rosa DeLauro said in an interview. “We may leave here today, but everybody is going home to a district where they’re going to take this fight on, and in addition to that we get back on July 5th and nothing changes. We’ve only just begun.”

Other Democrats reveled in the fact that they had been able to broadcast to a wide audience using social media. Beto O’Rourke, a Democratic congressman from Texas who live-streamed the Sit-in on Facebook, said, “In a one-hour period, when I was streaming, we received 10,000 comments.” He pointed to his social-media metrics as evidence of the event’s resonance. “There was obviously a lot of pent-up urgency and excitement about this.”

For now, it seems unlikely that House Democrats will win the votes they seek on gun control. But their agitation on the issue will probably continue, and maybe increase. —Clare Foran
