Sen. Bob Corker (R-Tenn.) said that President Trump’s threats to other countries could put the U.S. “on the path to World War III.”

Corker told The New York Times Sunday that Trump was treating the presidency like “a reality show” and acts “like he’s doing ‘The Apprentice’ or something.”

“He concerns me,” Corker told the Times. “He would have to concern anyone who cares about our nation.”

Corker’s comments come after Trump attacked the senator in a series of tweets on Sunday.

“It’s a shame the White House has become an adult day care center. Someone obviously missed their shift this morning,” Corker fired back in a tweet earlier Sunday.

Corker disputed Trump’s account to the Times, saying that Trump had asked him to run and promised to endorse him if he did.
