House Appropriations Committee Chairwoman Rosa DeLauro (D-Conn.) said Thursday that she is hopeful a bill to boost security at the Capitol will be introduced shortly, with a committee advancing the measure in the "next couple of weeks."

DeLauro said Democrats have held talks with Republicans in crafting the legislation, adding that the supplemental spending bill would focus narrowly on fixing security flaws exposed by the Jan. 6 attacks.

"Supplementals can become Christmas trees, and that, we're not going to do," she said at an event hosted by the Brookings Institution. "We are trying to avoid that like the plague."

The timeline laid out by DeLauro is similar to the one House Majority Leader Steny Hoyer (D-Md.) put forward in April.

Democrats are likely to huddle on the supplemental spending bill Monday before unveiling the legislation and sending it to the House Rules Committee for floor consideration.

The measure will deal with issues relating to the Capitol Police and its preparedness, beefing up the Capitol complex and providing members of Congress additional security.

Since the January insurrection, in which a mob of former President Trump's supporters sought to overturn the results of the 2020 election, Congress has been conducting investigations and holding hearings focused on the massive security breach.

The supplemental spending bill will including funding for new training, equipment and intelligence operations based on the findings of those probes and hearings. It will also provide funds for hardening windows and doors and potentially fencing, an increasingly controversial topic.

One option under consideration is a retractable fence, which could easily be raised during emergencies or times of higher security alerts.

"What we want to do is maintain a balance between accessibility to the Capitol and safety," DeLauro said Thursday.

Further security funding could be included in the Legislative Branch Appropriations bill for 2022.

DeLauro also said the regular appropriations committee and subcommittee markups for the 2022 fiscal year would take place in June, with floor passage in the House expected in July.
