Fox News host Chris Wallace announced on his Sunday show that he is resigning from the network after 18 years, saying he is “ready for a new adventure,” which he said following the broadcast was moving to CNN’s streaming service.

“After 18 years — this is my final ‘Fox News Sunday.’ It is the last time — and I say this with real sadness — we will meet like this,” Wallace said during his final broadcast with the network.

The “Fox News Sunday” anchor concluded his farewell message by telling viewers that he is grateful they have chosen to spend their Sundays watching his show and hopes they will follow him as he tackles “a new adventure.”

Fox News Media said in a statement following the anchor’s announcement that the company is “extremely proud of our journalism and the stellar team that Chris Wallace was a part of for 18 years” and that “Fox News Sunday” will have a number of their star hosts rotating in until they select a permanent replacement.

Wallace’s new adventure: joining rival network CNN’s streaming service, CNN+, as a host of a weekday show featuring interviews with people involved in politics, business, sports, and culture, CNN said in a statement.
