Senator Bob Corker, the Republican chairman of the Senate Foreign Relations Committee, charged in an interview on Sunday that President Trump was treating his office like “a reality show,” with reckless threats toward other countries that could set the nation “on the path to World War III.”
In an extraordinary rebuke of a president of his own party, Mr. Corker said he was alarmed about a president who acts “like he’s doing ‘The Apprentice’ or something.”
“He concerns me,” Mr. Corker added. “He would have to concern anyone who cares about our nation.”
The senator, who is close to Mr. Tillerson, invoked comments that the president made on Twitter last weekend in which he appeared to undercut Mr. Tillerson’s negotiations with North Korea.
“A lot of people think that there is some kind of ‘good cop, bad cop’ act underway, but that’s just not true,” Mr. Corker said.
Without offering specifics, he said Mr. Trump had repeatedly undermined diplomacy with his Twitter fingers. “I know he has hurt, in several instances, he’s hurt us as it relates to negotiations that were underway by tweeting things out,” Mr. Corker said/
“Look, except for a few people, the vast majority of our caucus understands what we’re dealing with here,” he said, adding that “of course they understand the volatility that we’re dealing with and the tremendous amount of work that it takes by people around him to keep him in the middle of the road.”
As for the tweets that set off the feud on Sunday morning, Mr. Corker expressed a measure of powerlessness.
“I don’t know why the president tweets out things that are not true,” he said. “You know he does it, everyone knows he does it, but he does.”
