Tucker Carlson has parted ways with Fox News, which said, “We thank him for his service to the network as a host and prior to that as a contributor,” in a statement.

Carlson’s last show was Friday, and Fox has said it will be airing a new program called “Fox News Tonight” starting Monday evening as an interim show, led by rotating Fox News personalities until a new host is named.

Carlson was Fox’s top-rated prime time host, netting an average of more than 3 million viewers per night.
