Stephen Colbert isn't holding back his words when it comes to Donald Trump.
In an upcoming interview with Bill Carter on SiriusXM, the late-night talk show host calls the Republican presidential nominee a "coward" and a "chicken" for not returning as a guest on CBS' The Late Show.
After clucking and squawking to drive the point home, Colbert says wryly, "He's got a great sense of humor about himself. I'm sure he won't mind."
Carter joins in the teasing too: "Come on, Donald. Step up," the host encourages.
The rambunctious interview takes a couple other amusingly controversial turns, as well. Colbert dismisses the popular daily USA Today as "a cartoon page masquerading as a newspaper," calling attention to the paper's unprecedented nonendorsement of Trump.
Carter, a longtime New York Times reporter and recently a Hollywood Reporter columnist, is currently a CNN contributor.
The full conversation airs on SiriusXM Insight on Monday on channel 121.
