Chris Wallace says he left Fox News after people at the news organization began to question matters of truth, like the Jan. 6 riot and whether the 2020 election was stolen.

Wallace said he spent a lot of time looking for a new place to do his job after having become alarmed at the shift he said he felt.

“I’m fine with opinion: conservative opinion, liberal opinion,” Wallace told The New York Times. “But when people start to question the truth — Who won the 2020 election? Was Jan. 6 an insurrection? — I found that unsustainable.”
