Stephen Colbert's friends and colleagues are in shock at The Late Show's surprise cancellation.

CBS’ decision to cut ties with Stephen Colbert and its decades-old “Late Show” franchise come next May will leave a major hole in the format — but one that has been widening. TV networks have been cutting costs at their late-night mainstays for the past few years.

“ Late Show ” host Stephen Colbert went after President Donald Trump on Thursday, the same day it was announced that his show had been canceled. And he focused on two issues the president does not like to talk about: his health, and his links to the late convicted sex offender Jeffrey Epstein.
