Top Republican warns that Trump is putting US on course for WWIII with his impulsive threats

A top Republican lawmaker warned Sunday that US President Donald Trump’s impulsive threats against other countries could set America “on the path to World War III”, in comments capping an unusually hostile and public feud between the pair on social media.

Bob Corker, who chairs the powerful Senate Foreign Relations Committee, slammed the president for running his office like a “reality show” in a stinging rebuke against a sitting president of his own party that was remarkable even by the volatile standards of the Trump administration.

The public spat between the former allies could also undermine Trump’s legislative agenda, with Corker’s vote vital to the fate of the Iran nuclear deal and passing tax reform.

“He concerns me,” Corker told The New York Times, adding: “He would have to concern anyone who cares about our nation.”

The drama erupted in the morning, when Trump tweeted that Corker had decided against running for re-election because he lacked the “guts” and the senator replying that the White House had become an “adult daycare centre.”
