Bill O'Reilly Refuses to Apologize For Calling Putin a Killer

Bill O'Reilly is refusing to back down from calling Vladimir Putin a murderer, and insists he won't be saying sorry ... at least not anytime soon.

Bill just addressed Mr. Putin on his TV show after Putin's spokesman demanded an apology from FOX when its host called Putin a "killer" while interviewing President Trump.

O'Reilly's response, in a word -- nyet! Unless Putin's still running the show in 2023.
