Senate Republicans on Wednesday officially moved ahead with a reconciliation proposal funding the Department of Homeland Security after removing a $1 billion Secret Service appropriation tied to security upgrades associated with President Donald Trump's White House ballroom project.

Construction on the ballroom is underway where the East Wing once stood, and it's unclear how the Senate's decision will affect the project.

Trump has said the ballroom would be funded through private donations, including contributions from himself.

Last month, the Senate Judiciary and Homeland Security committees unveiled the initial text of the $72 billion package, which funds immigration agencies through fiscal 2029, roughly the end of Trump's second term.

The original text included $1 billion for "security adjustments and upgrades" tied to the ballroom project and other security measures raised after the assassination attempt against Trump during the White House Correspondents' Association dinner in April.

Administration officials later said only about $200 million would go toward the ballroom project, with the remainder funding other security efforts.

Senate GOP leaders had acknowledged that the language would have derailed the entire immigration package politically and procedurally after the Senate parliamentarian determined that it violated the budgetary rules governing reconciliation bills.

They agreed before the Memorial Day recess to remove the funding from the reconciliation package, according to The Hill, but made the decision official Wednesday.

If the language had remained in the bill, it would have required 60 votes to advance, meaning Democrats could have filibustered the measure and prevented the Trump administration from receiving roughly $70 billion for Immigration and Customs Enforcement and Customs and Border Protection.

The White House suggested the change was the result of parliamentary rules rather than political pressure on Republicans.

Trump has urged Senate Republicans to fire Parliamentarian Elizabeth MacDonough, who was appointed by then-Senate Majority Leader Harry Reid in 2012. She is the first woman to hold the position.

"The parliamentarian's decision was reported weeks ago," the White House said in a statement, according to CNN. "This framing is false, as it implies that Republicans removed it deliberately rather than under parliamentary pressure."

The Senate on Wednesday began a series of procedural votes aimed at passing the package and sending it to the House for final approval.
