July 20 (Reuters) - U.S. President Donald Trump threatened on Sunday to interfere with a deal to build a new football stadium in Washington, D.C., unless the local NFL team, now known as the Commanders, changes its name back to Redskins.

The American football team dropped the name Redskins in 2020 after decades of criticism that it was a racial slur with links to the U.S. genocide of the Indigenous population.

Trump had called for a return to the name Redskins - and for the Cleveland Guardians baseball team to once again adopt the name Indians - on other occasions, but on Sunday he added that he may take official action.

"I may put a restriction on them that if they don’t change the name back to the original 'Washington Redskins,' and get rid of the ridiculous moniker, 'Washington Commanders,' I won’t make a deal for them to build a Stadium in Washington," Trump said in a post on his Truth Social platform.
