“Your decision to withdraw at the last moment — explicitly in response to the Center’s recent renaming, which honors President Trump’s extraordinary efforts to save this national treasure — is classic intolerance and very costly to a non-profit Arts institution,” Grenell wrote in a letter to Redd that was shared with the Associated Press.

Redd had performed at the Kennedy Center annually since 2006, but said he canceled his concert over the name change.

“When I saw the name change on the Kennedy Center website and then hours later on the building, I chose to cancel our concert,” Redd said.

The Kennedy Center was renamed earlier this month after a unanimous vote by its Trump-appointed board. The center’s new name is on both its website and the building itself, but it’s unclear if the change is legal.

Rep. Joyce Beatty (D-OH), an ex officio board member at the center, filed a lawsuit on Dec. 22 challenging the move, arguing the board does not have the legal authority to change the center’s name. Federal law designated the center’s name as a memorial to former President John F. Kennedy.

Trump chose Grenell to lead the Kennedy Center after he had ousted most of the previous board of trustees.

Roma Daravi, vice president of public relations at the Kennedy Center, related to much of Grenell’s sentiment in comments to CNN.

“Art is a shared cultural experience meant to unite, not exclude,” Daravi said. “The Trump Kennedy Center is a true bipartisan institution that welcomes artists and patrons from all backgrounds — great art transcends politics, and America’s cultural center remains committed to presenting popular programming that inspires and resonates with all audiences.”
