Tucker Carlson to interview Russia's Putin
In a video posted on X, formerly Twitter, Carlson said he wanted to do the interview because "Americans have a right to know all they can about a war they are implicated in".
"There are risks to doing an interview like this, obviously, so we've thought about it over many months," Carlson said on his announcement video.
Carlson added that he paid for the trip to Russia himself, and wanted to do the interview because "most Americans are not informed" on the conflict which is "reshaping the world" - blaming the mainstream media.
But they are "fawning pep sessions" aimed at amplifying Mr Zelensky's demand to get the US more and more involved in the war, Carlson insisted.
Steve Rosenberg, the BBC's Russia Editor, posted that the BBC has "lodged several requests with the Kremlin in the last 18 months. Always a 'no' for us".
And the International Criminal Court (ICC) has issued an arrest warrant for Vladimir Putin, accusing him of war crimes and the unlawful deportation of children from Ukraine to Russia.
Tucker Carlson has been an outspoken defender of Mr Putin since the war began. Just before Russia's invasion, he claimed that "hating Putin has become the central purpose of America's foreign policy", but urged his viewers to ask themselves why.
"Has Putin ever called me a racist? Has he threatened to get me fired for disagreeing with him?" Carlson said as Russian troops started to mass on Ukraine's border. "These are fair questions, and the answer to all of them is: No. Vladimir Putin didn't do any of that."
After Russia had invaded, he changed his tone slightly during a different show, saying "Vladimir Putin started this war... He is to blame for what we're seeing tonight in Ukraine".
Exactly when the interview will take place is unclear, but Carlson said it would be uploaded live and unedited to his X account. Elon Musk, who owns the platform, has "promised not to suppress or block the interview".
