In a statement, Fox News praised the show's performance in the ratings as "consistently strong."The 7 p.m. slot will be taken over by Martha MacCallum, co-host of America's Newsroom, for the first 100 days of Trump's presidency.Carlson was a print journalist in the '90s, writing for publications such as The Weekly Standard and Esquire. He began his television career with CNN, where he co-hosted The Spin Room and Crossfire. More recently, he co-founded the conservative news website The Daily Caller; he stepped down as an editor to focus on Tucker Carlson Tonight.Carlson has occasionally spoken to NPR in the role of a commentator, usually alongside commentator Cokie Roberts.Update at 2:45 p.m. ET: Another media moveFormer Fox News anchor Greta Van Susteren is moving to MSNBC. She will host a 6 p.m. ET weeknight show called For the Record with Greta, which will debut on Monday. MSNBC President Phil Griffin said in a statement that Van Susteren's "broad range of experience and sharp news judgment will be of great value to MSNBC as we build on our momentum going into a new year and a new administration."Van Susteren left Fox News in September 2016.
