A Democratic senator alleged Saturday that whistleblowers have detailed several problems stemming from the hasty or inadequate reconstruction of the Kennedy Center, adding a new layer to the arts complex’s travails as President Donald Trump sought to seize control of it and its name.

Sheldon Whitehouse of Rhode Island said in a statement Saturday that he had received a whistleblower tip from the Government Accountability Project, a nonprofit whistleblower protection group, alleging that “the Center rushed a series of renovations driven by the President’s aesthetic whims and his desire to star in a series of televised events in December.”

“The Center’s submission to the President’s wishes and its short-cut hiring practices have resulted in steel columns that are rusting through fresh paint, a reflecting pool that may have to be torn out and rebuilt, and a new bathroom floor ripped up by an offensive tile color,” Whitehouse continued. “This is wasteful and treats a national memorial to President Kennedy as if it were a private renovation project.”

The Kennedy Center did not immediately respond to a request for comment.

Trump took control of the arts and cultural venue, named after former President John F. Kennedy, at the beginning of his second term. Trump ousted the center’s previous leadership and replaced it with a board of directors that named him president and added his name to the building.

Democrats sued to remove it, and a federal judge ruled that Trump’s name must be removed from the venue, which had been plagued by boycotts by artists during the unrest. He tried to close the center for two years, but the court ordered him to keep it open because only Congress could change the name.

Whitehouse released a letter he wrote to the center’s executive director, Matt Floca, demanding answers by July 23. He said the whistleblower report included “first-hand accounts from multiple former Center project managers, supported by contemporary documents and photographs.” It also included an 83-page appendix filled with internal center documents, emails and photographs of apparently shoddy construction.

Allegations include that the center rushed the work before it was authorized by Congress because it wanted it to be complete for Trump to accept the new FIFA Peace Prize awarded to him by the soccer federation. In doing so, the letter alleges that the center failed to follow required contracting guidelines and wasted money replacing a bathroom because the president didn’t like the color and signed no-bid contracts. An $8 million contract to replace the concert hall floor was awarded to a company with no concert hall experience, Whitehouse said.
