Former Fox News anchor Chris Wallace explained in a recent interview his reason for departing from the network in December, saying top network opinion hosts questioning “the truth” regarding the 2020 election and the Jan. 6 Capitol riot made working for the company “unsustainable.”

During an interview with The New York Times, published Sunday, Wallace said he “just no longer felt comfortable with the programming at Fox.”

Wallace worked for Fox News for 18 years, anchoring “Fox News Sunday” and hosting numerous presidential debates. Just hours after his announcement to leave the network, CNN said he would be joining its new streaming service, CNN+, as a host of a weekday program that will feature interviews with people involved in politics, business, sports and culture. Wallace’s show – “Who’s Talking to Chris Wallace?” – launches Tuesday.
