Senate Majority Leader John Thune said on Monday the funding reflected the rising cost of protecting the president following recent security threats, including an incident last month in which a man was charged with attempting to assassinate Trump during the White House Correspondents’ Association dinner.

“Keeping the leader of the free world safe is an expensive proposition,” Thune told reporters as lawmakers returned to Washington after recess.
The proposed funding was added by Senate Republicans to a broader spending package designed to restore financing for immigration enforcement agencies after months of budget disputes with Democrats.

Trump has previously said the ballroom itself, projected to cost roughly $400 million, would be financed privately. The White House had not previously disclosed estimates for associated security expenditures.

Democrats sharply criticized the measure, accusing Republicans of using national security arguments to justify taxpayer support for a project they say primarily serves Trump’s personal and political interests.
Senate Democratic leader Chuck Schumer said the proposal contradicted earlier assurances from Trump that public funds would not be used for the development.

“This staggering waste of taxpayer dollars has nothing to do with security and everything to do with Trump’s ego,” Schumer said.

Republicans are advancing the legislation through a budget reconciliation mechanism that would allow passage in the Senate without Democratic support. Democrats said they would challenge the measure procedurally and seek amendments aimed at stripping the ballroom-related funding from the bill.
The proposal has also prompted questions from some Republican lawmakers seeking additional details on how the money would be spent.

Representative Rob Wittman said he wanted a clearer explanation of the planned expenditures before deciding whether to support the measure, while Representative Mike Haridopolos said lawmakers needed to balance security concerns with fiscal scrutiny.

The Senate legislation directs funding to the United States Secret Service for “security adjustments and upgrades” associated with the ballroom project, including above-ground and subterranean protective infrastructure. The bill specifies the money cannot be used for non-security construction costs.

According to court filings cited by the White House, the proposed East Wing expansion would include hardened defensive features such as bomb shelters, military-grade installations and a medical facility beneath the ballroom complex. Trump has also said the structure should incorporate bulletproof glass and defenses against drone attacks.

White House spokesperson Davis Ingle said the funding would help the Secret Service strengthen protections around the White House complex and support broader operational requirements.
The project remains the subject of ongoing legal challenges.

The National Trust for Historic Preservation has sued to halt construction, although a federal appeals court ruled last month that work could continue while litigation proceeds.
