Fox News’ top-performing host Tucker Carlson is leaving the network after appearing in the prime-time slot since November 2016.

“Fox News Media and Tucker Carlson have agreed to part ways. We thank him for his service to the network as a host and prior to that as a contributor,” the company wrote in a statement.

The sudden departure did not leave Carlson time to host a final farewell episode of his wildly successful program Tucker Carlson Tonight. His last episode was broadcast on Friday, April 21, the network said.

An interim show featuring a rotating cast of Fox News personalities will fill the 8 p.m. hour until a new host is named.
