WASHINGTON (AP) — The House on Thursday narrowly approved $1.9 billion to fortify the Capitol after the Jan. 6 insurrection, as Democrats pushed past Republican opposition to try to harden the complex with retractable fencing and a quick-response force following the most violent domestic attack on Congress in history.

The bill’s 213-212 passage came a day after the House approved the formation of an independent commission to investigate the deadly mob siege by President Donald Trump’s supporters, who battled police to storm the building in a failed attempt to overturn Democrat Joe Biden’s election.

The two measures now face an uncertain outcome in the evenly divided Senate as most Republicans have objected to both — and as some liberal Democrats opposed the security money over concerns about policing. Three Democrats voted against the spending bill and three voted “present” as House Speaker Nancy Pelosi and other Democratic leaders lobbied their own members during the vote to ensure passage.

The legislation to form the commission passed much more easily on Wednesday, with 35 Republicans joining all Democrats to vote for it. Still, Senate Democrats could have trouble persuading enough Republicans to vote with them after Senate Republican Leader Mitch McConnell announced he would oppose the inquiry.

Democrats grew frustrated during the debate on both bills, charging that Republicans are looking away from the insurrection that they witnessed themselves out of fealty to Trump.

“We have a major political party in the country that’s ignoring it — we’re trying to solve a problem, they clearly don’t want to sit down and talk about it,” said Rep. Tim Ryan, D-Ohio, chairman of an appropriations subcommittee handling legislative branch security.

House Appropriations Committee Chairwoman Rosa DeLauro recalled her own experience being trapped in the House gallery that day as the attackers tried to break in, calling her husband to tell him she was OK after Capitol Police told her to duck on the floor.

“This bill is not about politics, it’s not about settling scores,” DeLauro said. “It’s about ensuring that every person who comes into the Capitol is safe and is protected.”

Republicans argued that the spending bill is too expensive and that no fencing is needed. Many of them said lawmakers should be spending money on border security, not Capitol security.

Rep. Lance Gooden, R-Texas, argued that Democrats would rather spend money on a wall “around this building in D.C.” than they would on finishing a border wall advocated by Trump.

The Democrats who opposed the security legislation were some of the most liberal in the House. Some have expressed the view that police treat people of color unfairly. Democratic Reps. Cori Bush of Missouri, Ayanna Pressley of Massachusetts and Ilhan Omar of Minnesota voted against it.

Those Democrats “wanted to make sure that there were accountability measures” on the security, said Washington Rep. Pramila Jayapal, a Democrat who voted for it. Omar said just before the vote that she had “not been convinced of the importance of the money.”

Democratic Reps. Alexandria Ocasio-Cortez of New York, Jamaal Bowman of New York and Rashida Tlaib of Michigan voted “present,” effectively saving the measure from going down to defeat.

Months in the making, the emergency spending package incorporates the recommendations from an outside panel of experts to beef up security after the violent mob attack.

Already, National Guard troops have been protecting the building for months and public access is severely limited. Though razor-wire-topped fencing that stood as a stark reminder of the siege has been removed, an extended perimeter fence remains in place, cutting off access to the lush grounds that have been popular with visitors.

The bill includes money for new fencing — either retractable or “pop in,” according to Democrats — that would protect the grounds while removing the current perimeter. The legislation says the money cannot be used to install permanent above-ground fencing, reflecting the wishes of most members of Congress that the area should be open to the public.

Other improvements would be to better secure windows and doors, install new security vestibules and cameras, and protect members with increased security at home and in Washington, as threats against them have doubled in the last year. There is also money to protect federal judges who are prosecuting the rioters and have received threats, and to repay the Capitol Police and other federal agencies for their efforts on Jan. 6.

The legislation renames a wellness program for Capitol Police as the Howard C. “Howie” Liebengood Center for Wellness and adds mental health counselors and resilience specialists for trauma support. Liebengood was a Capitol Police officer who took his own life shortly after the attack.

Some lawmakers have raised objections to the proposal for the National Guard to maintain a “quick response force” nearby — an effort to improve response time after it took hours for Guard troops to arrive on Jan. 6 as officers were being brutally beaten by the rioters.

Leading Republicans on the armed services committees in the House and Senate oppose relying on the troops for the work of protecting the Capitol, a sentiment shared by many members who have pushed to open the reopen the Capitol grounds immediately.

Democrats said they, too, are uneasy with many of the military-like measures, but say they have little choice but to protect the building. The delays in sending the Guard to the Capitol have been blamed in part for the failure to contain the violence. Five people died, including a Trump supporter shot and killed by police as she tried to climb through a broken window to access the House chamber, and a police officer who fought off the mob and died later.

“We’ve never had a quick response for us here, you know, we’ve never had an insurrection either,” Ryan said. “So thinking has to evolve in order to try to solve some of these problems.”
