Sen. Bob CorkerRobert (Bob) Phillips CorkerCheney set to be face of anti-Trump GOP How leaving Afghanistan cancels our post-9/11 use of force The unflappable Liz Cheney: Why Trump Republicans have struggled to crush her MORE said President TrumpDonald TrumpCheney says a lot of GOP lawmakers have privately encouraged her fight against Trump Republicans criticizing Afghan refugees face risks DeVos says 'principles have been overtaken by personalities' in GOP MORE called him on Wednesday and asked him not to move forward with legislation limiting some of his authority on trade, but the Tennessee Republican said he would do so anyway.
"I talked at length with the president about it today. He's obviously not pleased with this effort," Corker told reporters.
Corker said that the two had a "fairly lengthy" conversation about the forthcoming legislation. Asked if Trump was objecting to the legislation, Corker added: "Oh yeah."
Pressed if the talk with the president was "tense," Corker demurred, saying that they had a "heartfelt conversation."
Corker and a bipartisan group of senators are expected to unveil legislation later Wednesday to require Trump get congressional approval when he wants to implement tariffs under the national security provisions of the trade law, known as Section 232.
The GOP senator confirmed that he was planning to move forward with his bill regardless of Trump's objections, calling the fight a "legislative prerogative."
"He feels this takes away his negotiating ability," Corker said.
The legislation comes after the Trump administration sparked frustration by announcing last week that the U.S. would slap steep steel and aluminum tariffs on the European Union, Canada and Mexico, ending exemptions for the key trading allies.
Corker has pointed to the National Defense Authorization Act, which the Senate turned to on Wednesday, as one potential vehicle for his tariff legislation.
But getting the bill brought up for an amendment vote would require the consent of every senator, some of whom could be wary of picking a fight with the president.
"There are people here that probably have concerns about going against the president," Corker acknowledged Wednesday. [But] to me this is the kind of thing that should pass 100 to nothing."
