NEW YORK — Stephen Colbert has received support from his fellow late-night TV hosts following his cancellation by CBS, including from his predecessor. David Letterman, who was the host of “The Late Show” for 22 years, used his YouTube channel to post a video montage of the many times he ripped into CBS over the years for various reasons.

In his monologue, Colbert snapped back at President Donald Trump for hailing the cheering of the cancellation of ‘The Late Show.’
