Jason Miller, a former aide to President Trump, on Monday suggested Sen. Bob Corker (R-Tenn.) resign following his feud with the president, arguing Tennessee’s governor could appoint Rep. Marsha Blackburn (R-Tenn.) to take his place.

“And look, if Senator Corker is retiring and he doesn’t want to be in the U.S. Senate and he doesn’t want to support President Trump and doesn’t want to support such basic conservative principles, he should just resign,” Miller told CNN’s “New Day.”

“Let the governor of Tennessee go and appoint a conservative like Marsha Blackburn, the congresswoman who’s running to replace Senator Corker and get somebody in there who’s actually going to support the president.”
