Republican efforts to rename the Kennedy Center in honor of President Donald Trump, and to christen its Opera House after First Lady Melania Trump, are likely illegal, NBC News reported Monday. The report cited multiple congressional and legal experts who challenge the legality of the move because federal law strictly prohibits such renaming.

The move comes after last week's vote to rename the Washington D.C. arts center’s opera house after First Lady Melania Trump

The amendment comes as the latest move in Republicans' effort to reshape the Kennedy Center, which was authorized by President Dwight D. Eisenhower in 1958, named after President John F. Kennedy in 1964 following his assassination, and opened in 1971 under the Richard Nixon administration.
