Writer Michael A. Cohen, a contributing writer for The American Conservatives, will return to the fold after three decades.
Cohen will be the latest conservative journalist to leave Fox News following the departures of Tucker Carlson and Bret Baier.
He will be replaced by Mike Allen, who will continue as co-host of the Fox News Channel’s The Five.
The news will be greeted with excitement among conservatives, who had hoped to see a return to normalcy in the aftermath of a tumultuous year for the network, which has been engulfed in multiple controversies over its coverage of the 2016 presidential election.
But many of those controversies have already been resolved, including the firing of Fox News host Bill O’Reilly and a slew of other departures.
And as a result of the departures, The Five is now known as the most popular show on Fox News, with more than 40 million viewers and more than 20 million monthly viewers.
Cohens tenure on the network came to an abrupt end this summer after he criticized President Donald Trump’s response to the Paris attacks and criticized the White House for having a white nationalist president in the White the Oval Office.
Cooper will be joined on the show by his co-anchor, Bill Hemmer.
He was a longtime contributor to Fox News and has been a frequent guest on Fox’s shows.
He previously worked at the conservative blog The Federalist.
A Fox News spokesman did not immediately respond to a request for comment.
