As Donald Trump’s delegate numbers continue to climb, he’s starting to collect endorsements from everyone from New Jersey governor Chris Christie to boxer Mike Tyson.

Norman Seabrook, the president of New York City’s Correction Officers’ Benevolent Association (COBA), may soon join their ranks. Seabrook describes the billionaire as a friend, crediting him with creating “thousands of union jobs.”

This news may come as a surprise to the more than five hundred workers at Trump’s Las Vegas hotel who are currently locked in a bitter unionization campaign. Workers there face serious retaliation if they continue to push to form a union — one employee involved in the struggle was fired soon after workers voted to unionize late last year.
