U.S. journalist Tucker Carlson has reportedly left Russia following his interview with Russian President Vladimir Putin, while Ukraine remains conspicuously silent on his request to interview Ukraine's leader Volodymyr Zelenskyy.

The interview will be broadcast later Thursday on X and Carlson's media startup at 18:00 ET.
