The visit from Cotton — one of the Senate’s most hawkish lawmakers — comes in the waning days of congressional review of the nuclear deal with Iran, ahead of a vote to kill the agreement next month.

Cotton and Netanyahu have both vigorously opposed the pact, which they say will only ensure Iran’s path to a nuclear weapon and increase its ability to support terrorism across the region.

“Today’s meeting only reaffirms my opposition to this deal,” Cotton said in a statement after the meeting. “I will stand with Prime Minister Netanyahu and Israel and work with my colleagues in Congress to stop this deal and to ensure that Israel has the means to defend itself against Iran and its terrorist surrogates.”

Cotton has repeatedly railed against the deal, which was signed by the U.S., Iran and five other nations earlier this summer. In particular, he has been the most vocal critic of side deals to the agreement between Iran and the International Atomic Energy Agency that outline the terms of international inspectors' visits to Iran’s facilities.

Netanyahu and other prominent Israeli leaders have been among the most active outside voices encouraging Congress to halt the accord.

Still, Cotton and fellow Republicans appear likely to fall short of that goal. Though GOP lawmakers appear to have united to block the deal, only two Senate Democrats have so far committed to join them.
