Jeb Bush said he thinks a fellow Republican should challenge President Donald Trump in 2020, according to a portion of an interview for the series “The Axe Files.”

The excerpt was tweeted by show host David Axelrod, a commentator and ex-adviser to former President Barack Obama. Axelrod’s interview with Bush, who went up against Trump in the 2016 Republican primary, is set to air on CNN at 7 p.m. on Saturday.
