Senator Bob Corker (R-TN) speaks to reporters as he arrives for the weekly Senate Republican policy luncheon on Capitol Hill in Washington, U.S., April 17, 2018.
Trump has opposed terms that would allow Iran to gradually reinstate its nuclear activities and accused Iran of violating the agreement. Iran has said its nuclear program is only for peaceful purposes and its ballistic missiles solely for defense.
Corker, a two-term senator from Tennessee who won’t be seeking re-election, has played a key role in talks aimed at the preventing the deal from crumbling. He said a deal still could be reached if “there’s a framework agreement.”
But, “we’ve had some resistance from the EU three that we’ve been dealing with,” he said.
Iran’s nuclear deal was struck in 2015 with China, the United States, U.K., Russia, France and Germany.
Corker was an early supporter of Trump during the election and was floated as a potential running mate during the campaign. However, Corker later became critical of Trump’s behavior and at one point called Trump an “utterly untruthful president.”
Corker’s relationship with Trump has ebbed and flowed ever since.
