WASHINGTON (AP) — President Donald Trump’s handpicked board voted Thursday to rename Washington’s leading performing arts center as the Trump Kennedy Center, the White House said, in a move that made Democrats fume, saying the board had overstepped its legal authority.

Congress named the center after President John F. Kennedy in 1964, after his assassination. Donald A. Ritchie, who served as Senate historian from 2009-2015, said that because Congress had first named the center it would be up to Congress to “amend the law.”

Ritchie said that while Trump and others can “informally” refer to the center by a different name, they couldn’t do it in a way “that would (legally) stick.”

But the board did not wait for that debate to play out, immediately changing the branding on its website to reflect the new name:

House Democratic leader Hakeem Jeffries told reporters that legislative action was needed, “and we’re going to make that clear.” The New York Democrat is an ex officio member of the board because of his position in Congress.

“The Kennedy Center Board of Trustees voted unanimously today to name the institution The Donald J. Trump and The John F. Kennedy Memorial Center for the Performing Arts,” said Roma Daravi, the institution’s vice president for public relations.
