U.S. President Donald Trump’s name was removed from the facade of the Kennedy Center on Saturday, capping off the president’s longtime effort to assert control over the institution, one of Washington’s most iconic cultural landmarks.

In a Saturday court filing to the U.S. District Court for the District of Columbia, Matthew Floca, the Kennedy Center’s chief operating officer and executive director, confirmed work crews had removed “all physical signage” from the building and grounds “that purports to rename the Kennedy Center after President Trump or any individual besides President Kennedy.”

Workers, hidden behind a large white tarp, removed Trump’s name from the building’s white exterior early Saturday morning, after blowing past a Friday deadline due to what Floca cited as “weather-related delays.” The tarp remained in place on Saturday afternoon.

The removal comes after U.S. District Judge Christopher Cooper ruled in late May that Trump’s rebranding of the performing arts center in his own name was illegal, contravening federal law that the center could only honor Kennedy and usurping authority from Congress.

In the weeks since, officials have removed references to Trump on the Kennedy Center’s website, issued new identification cards, edited employee email signatures and rescinded any trademark applications adding Trump to the institution’s name, Floca wrote in his filing. The restoration of the building’s original name followed denials Friday by both Cooper and an appeals court of last-ditch attempts by the administration and Department of Justice to stay Cooper’s May ruling.

It’s a stinging blow to the president, whose ambitious plans for the Kennedy Center included packing its board with loyalists and shutting it down for two years to conduct major renovations.

Cooper, an appointee of former President Barack Obama, also nixed the Kennedy Center’s closure in his May ruling, prompting Trump to angrily announce plans to transfer the institution back to Congress in a Truth Social post shortly after.

“Judge Cooper should be ashamed of himself!” he wrote. “Unless I am free to do what I do better than anyone else, bring this Institution back, physically, financially, and artistically, I have no interest in continuing what could only be a hopeless journey into “NEVER NEVER LAND.”
