RABID COLBERT SHOOTS HIMSELF IN THE FOOT

Amps up potshots at bosses for axing his show

- 

WHINY windbag Stephen Colbert won’t quit publicly attacking his employers in the wake of his Late Night show being axed — but friends are urging the cranky comic to take a chill pill because he’s making himself look totally toxic and could be harming his future prospects, sources say.

“When his show was first canceled, people were on his side. His fellow late-night talk show hosts were backing him, and colleagues were cheering him on for sticking up for himself, but he’s doubling down too aggressively — and now support is waning,” an insider warns.
