Jon Stewart torched Fox News personality Tucker Carlson as a dishonest propagandist for, among other things, his questionable commentary on Russias aggression toward Ukraine.

Theres nothing you can take out of context with people like Carlson because none of it is real, comedian Stewart said on the latest episode of New York Times reporter Kara Swishers Sway podcast released Thursday.

You know, hes admitted when hes cornered, he lies. Its all a game and a performance, Stewart continued. I mean, honestly, I have no idea what the fuck that guy believes, truly.

Carlson last week defended Vladimir Putin amid Russias advances on Ukraine, noting among other things that the Russian president had never called him a racist or threatened to get him fired.

Since Russias military invasion, Carlson has toned down his pro-Russia rhetoric and admitted he was wrong to downplay the crisis but snidely blamed Vice President Kamala Harris for his mistake.

Swisher suggested Carlson had given Putin a pass because he hadnt done anything personal to him. Well, he did not take your parking space, Jon. Thats what it read like to me, she said.

Well, isnt that the way we judge dictators and atrocities? responded Stewart. Are they nice to me? You know, this Hitler guy? You know, yes, has he done some things? But I gotta tell you something, always holds the door, very polite.

Stewart later questioned why Fox founder Rupert Murdoch was trying to destroy the fabric of this country.

I dont know if its ideological or he just thinks, this is where the money is, Stewart said. But how somebody can in good conscience put a shithead like that on television every night to say those types of things? Thats where the responsibility lies in my mind.
