(The Post Millennial) – On Sunday, Fox News anchor Chris Wallace announced that is departing the network “effective immediately,” and will be joining CNN+ to host a weekday show. Wallace announced his abrupt departure at the end of Fox News Sunday, the show which he had hosted since 2003, according to CNN.

“After 18 years, I have decided to leave Fox. I want to try something new to go beyond politics, to all the things I’m interested in. I’m ready for a new adventure. And I hope you’ll check it out. And so, for the last time, dear friends, that’s it for today. Have a great week. And I hope you’ll keep watching Fox News Sunday,” Wallace said on-air during his final sign-off.

CNN announced that Wallace would be joining CNN+, the news network’s streaming platform launching in early 2022. He will host a show featuring interviews with newsmakers “across politics, business, sports and culture.”

“I am thrilled to join CNN+. After decades in broadcast and cable news, I am excited to explore the world of streaming. I look forward to the new freedom and flexibility streaming affords in interviewing major figures across the news landscape — and finding new ways to tell stories,” Wallace said in a statement.

Following Wallace’s departure, Fox News stated that it will rotate hosts on Fox News Sunday until a permanent host is named.

A long-term contract between Wallace and Fox News that had been renewed in 2017 was expiring this year, and Wallace decided he did not want to renew, a person familiar with the matter told CNN.

During Reliable Sources on Sunday, show host Brian Stelter talked about Wallace’s departure, confirming to viewers that Wallace was leaving Fox News for CNN.

“Fox News veteran, always defined by his Sunday morning moderating and his willingness to take on all political figures, right, left and everywhere else. Wallace, a veteran of Fox, now heading over to this house, to CNN. And according to the press release, he’ll be hosting a weekday show on CNN+ the streaming service so instead of Sundays, he will be on five days a week,” said Stelter.

Twitter users responded to Wallace’s sudden departure Sunday morning, with some issuing well wishes, and others criticizing the move.
