House Democrats have ended their marathon sit-in on the chamber’s floor that they staged to demand gun-safety legislation in the wake of the Orlando massacre.

Democrats took over the House floor at 11:30 a.m. Wednesday and ended their sit-in 25½ hours later in a protest that was broadcast live to the world over social media.

There were no indications that Republicans — who control the House — have met the Democrats’ demands.

Democrats wanted votes on bills strengthening background checks and barring firearms sales to people on the government’s no-fly list.

The Democrats were declaring victory anyway.

One of the protest leaders, civil rights veteran Rep. John Lewis of Georgia, said: “We are going to win this struggle.”

Republicans, who assailed the Democrats for the sit-in, had adjourned the chamber around 3:15 a.m. until after the Fourth of July.

By 6:30 a.m. Thursday, some 16 Democrats remained, including Minority Leader Nancy Pelosi, giving speeches and vowing to never retreat in their drive to curb firearm violence.

“We’re not taking a break from this effort,” Pelosi (D-Calif.) told about a dozen colleagues after 7 a.m., the Washington Post reported. “We will not rest.”

Pelosi turned down the requests of a US Capitol police officer, who asked the lawmakers to briefly leave the chamber during a standard morning security sweep.

“We won’t be able to do that,” she told the cop. “Perhaps later in the day.”

A few hours earlier, Rep. Al Green (D-Texas) said: “While the Americans don’t always expect us to win, they do expect us to fight. We demonstrated to the Americans why we can’t get votes on common-sense safety measures.”

When Republicans left earlier, Democrats remained on the House floor, shouting, “No bill, no break!” and waving papers with the names of gun victims written in black.

Rep. Maxine Waters of California said she was prepared to stay “until Hell freezes over.”

The House drama began after Democrats took over the chamber’s proceedings Wednesday — prompting Republican Speaker Paul Ryan to gavel the House into session late at night.

Ryan, who dismissed the theatrical protest as a “publicity stunt,” refused to allow votes on the two bills demanded by Democrats, involving background checks and no-gun-buy lists, AFP reported.

Instead, he called for votes on unrelated issues as he sought a return to order.

Ryan (R-Wis.) said the bills pushed by Democrats would take away people’s constitutional rights and deprive them of due process.

He noted that similar legislation was already rejected in the Senate earlier in the week.

With a crowd cheering them on from outside the Capitol during the night and many more following the proceedings on social media, Democrats declared success in dramatizing the call for action to combat gun violence.

“Just because they cut and run in the dark of night, just because they have left doesn’t mean we are taking no for an answer,” said Pelosi.

Lewis, who had participated in the civil rights sit-ins in the South in the 1960s, said Democrats had “crossed one bridge.”

“We have other bridges to cross,” he said, adding that Democrats “made a down payment on ending gun violence” in America. “We will continue to fight. … When we come back in July, we’ll start all over again.”

Rep. Katherine Clark (D-Mass.), who is credited with coming up with the idea and helping to recruit Lewis, said he “gave us all the resolve and the grit and determination to see this through when we are back in July,” the Washington Post reported.

The sit-in included over 100 House Democrats taking to the floor, waving signs naming victims of gun violence and singing “We Shall Overcome.”

During the sit-in, the cameras normally used for C-SPAN broadcasts, which are controlled by the House, were turned off, as were microphones. C-SPAN carried footage via the livestreams from members’ smartphones, the paper reported.

Throughout the day, the Democrats assailed the GOP’s refusal to bring gun-control measures to the floor. They taped rainbow-colored signs that said “Disarm hate” to all of the speaking podiums.

As the sit-in dragged into the night, they brought pillows, blankets and snacks to prepare for the long haul.

At 10 p.m. Wednesday, an exasperated Ryan took to the floor to call a vote on an unrelated measure, hoping to end the sit-in, but the Democrats chanted “Shame!” at him, the Washington Post reported.

By 2:30 a.m., Republicans moved up a vote to provide funding for the Zika virus — a bill Democrats haven’t agreed to.

“Democrats can continue to talk, but the reality is that they have no end-game strategy … and no stunts on the floor will change that,” said AshLee Strong, Ryan’s press secretary, the paper reported.

Outside the Capitol, Lewis addressed a group of about 150 gun-control advocates on the Capitol lawn.

“By standing here tonight, by standing with us, you’re bearing witness to the truth; you must never, ever give up or give in or give out,” he said, the Washington Post reported. “We got to stop the violence and do something about the proliferation of guns.”

Pressure had been building on both sides of the Capitol in the wake of the shooting rampage at the Pulse gay nightclub in Orlando, Florida, that killed 49 people and injured 53 others. The assailant, Omar Mateen, also died in the incident.

The mass shooting followed similar tragic incidents including the school shooting in Newtown, Connecticut.

The agitation for action caused a Senate filibuster last week and led to the chaos on the House floor.

Republicans had staged a similar protest in 2008. Democrats controlling the House at the time turned off the cameras amid a GOP push for a vote to expand oil and gas drilling. Republicans occupied the floor, delivering speech after speech after Pelosi, then the House speaker, sent lawmakers bolting to their August recess. Pelosi at that time had ordered the cameras turned off.

The showdown comes as a poll this week showed that support for stronger gun control measures has increased by 9 percentage points in recent days.

The CNN/ORC poll, released Monday, found that 55 percent of Americans are in favor of stricter gun laws, with 42 percent opposed — matching the highest level of support since the poll was taken in January 2013, a month after the Newtown shooting.
