In the event of a federal government shutdown, President Donald Trump will not attend an event at his resort at Mar-a-Lago Friday night, according to a White House official.

The president and first lady Melania Trump are scheduled to depart the White House for Trump’s Mar-a-Lago resort in Florida at 4:10 p.m. on Friday, but the president’s schedule will be modified if a shutdown appears likely, The Hill reported. The Trumps are planning to attend an event at Mar-a-Lago marking the one-year anniversary of his inauguration.

The White House official said that Trump’s Friday schedule is being adjusted so that the president can remain in Washington, D.C., until the Senate passes the spending bill.

“He can’t go until it’s done,” White House official said.

Lawmakers are working to pass a bill to temporarily fund the government before a Friday night deadline.

The one-year anniversary event scheduled at Mar-a-Lago will be hosted by Republican National Committee Chairperson Ronna Romney McDaniel and casino mogul Steve Wynn, and will raise funds for Trump’s reelection campaign and the RNC. Tickets to attend the event were priced at $100,000 each.
