As chairman of the foreign relations panel, Corker, Tenn., will help determine the future of the Iran nuclear deal, and his support will be critical in passing broad tax cuts.
Corker fired back, saying Trump's claim was entirely false and that it was a "shame the White House has become an adult day care center".
"Every single day at the White House", Corker said, "it's a situation of trying to contain him". "Someone obviously missed their shift this morning".
However, Trump is alleged to have remarked to associates that Corker, whose height is 5-foot-7, was too short for the top diplomat position.
The White House on Tuesday escalated its feud with Sen.
Sanders appeared ready to criticize Corker throughout the press conference. I said "NO" and he dropped out (said he could not win without.my endorsement). "We're on the right path right now, believe me". "Didn't have the guts to run!"
"I understand we're on the record", Corker said at the beginning of the phone call with The New York Times. "We need HealthCare, we need Tax Cuts/Reform, we need people that can get the job done!"
Corker that evening spoke with New York Times reporters and said he is concerned that Trump is running his White House and the federal government like "a reality show".
"He worked with them on the legislation that rolled that out", Sanders responded.
Ulterior motives? Pascal-Emmanuel Gobry of the Week calls Corker a hypocrite for his sudden public turn on the president and suggests that the retiring senator is positioning himself to be an "establishment" primary challenger to the president in the 2020 election.
Corker also looks to play a key role in the upcoming debate over taxes.
"I think we're well on our way, ' Trump said of Republican efforts to craft the bill".
In his speech at the United Nations General Assembly last month, Trump threatened that the United States "will have no choice but to totally destroy" DPRK if forced to defend itself or its allies.
