Days after news circulated that “The Late Show With Stephen Colbert” had been canceled, another show is under fire.

Kimmel, who has been engaged in a years-long feud with Trump, didn’t appear fazed by the president’s claim. “I’m hearing you're next,” he wrote on his Instagram Story. “Or maybe it’s just another wonderful secret.”

What’s happening now is not only wrong, it goes against what we must stand for as a nation," said Robert Suttmann, president of Local 802 American Federation of Musicians.

The union says of the Colbert cancellation, "Now, more urgently than ever, is a time for courage, not cowardice."
