Washington (CNN) Former White House chief strategist Steve Bannon is calling for Sen. Bob Corker to resign after a public feud between President Donald Trump and the Tennessee Republican boiled over this week.

"If Bob Corker has any honor, any decency, he should resign immediately," Bannon said in an interview with Fox News' Sean Hannity on Monday night.

Corker and Trump exchanged insults on Twitter over the weekend, and in an interview with The New York Times published Sunday , Corker said Trump is acting "like he's doing 'The Apprentice' or something," and added that he could set the nation "on the path to World War III."

Last week , Corker praised Trump's inner circle while taking a jab at the commander in chief, and said Secretary of State Rex Tillerson, Defense Secretary James Mattis and White House Chief of Staff John Kelly "help separate our country from chaos."

Corker has announced he will not run for re-election after 2018.
