Congressional Republicans are pushing legislation to authorize $400 million for the construction of a secure ballroom facility at the White House, according to multiple sources familiar with the proposal.

The initiative is being led by Senator Lindsey Graham of South Carolina and other Senate Republicans, who are advocating for a 90,000-square-foot ballroom facility. Supporters of the measure argue the project is essential for national security purposes.

The proposal comes amid what sources describe as recent security incidents, including an attempted breach at a White House Correspondents' Association dinner event over the weekend. Republican lawmakers have cited such incidents as justification for enhanced security infrastructure.

Meanwhile, House Speaker Mike Johnson indicated Monday that he has concerns about language in a separate bipartisan Senate bill related to Department of Homeland Security funding. Johnson stated he has developed a "modified" version of that measure, describing portions of the original Senate bill as "problematic."

The ballroom proposal is moving forward as House Republicans face what some are calling a challenging week in Washington, with lawmakers working to align House and Senate positions on various budget and security-related measures. The timing coincides with ongoing discussions about emergency funding for Immigration and Customs Enforcement and Customs and Border Protection.

The $400 million price tag for the ballroom project represents a significant federal expenditure that would require congressional approval through the normal legislative process.
