WASHINGTON (Reuters) - The No. 2 U.S. House of Representatives Republican, Majority Leader Kevin McCarthy, said on Friday he was committed to working with President Donald Trump to fix the Iran nuclear agreement but did not advocate ending the deal. McCarthy is one of the congressional leaders allowed under a 2015 law to introduce legislation that, if passed, would have immediately reimposed U.S. sanctions on Iran’s nuclear program lifted under the international nuclear accord. His comment was an indication that the Republican-controlled Congress does not intend to pursue that course.
