Republicans in Congress who vigorously opposed Donald Trump’s run for president are now preparing to work with the incoming Trump administration on a number of foreign policy and national security issues where their policies overlap. First on their agenda is drastically increasing sanctions on Iran.

“There are several issues that I can work with the new president on, the Iran deal being number one,” Sen. Lindsey O. Graham (R-S.C.), who voted for independent candidate Evan McMullin, told me. “Trump has been right about the Iran deal, it needs to be renegotiated. I’m going to create leverage for him.”

On the first day Congress is back in session, Graham said he and Senate Armed Services Committee Chairman John McCain (R-Ariz.) will reintroduce the Iran Ballistic Missile Sanctions Act, which was first introduced by outgoing Sen. Kelly Ayotte (R-N.H.).

The legislation would expand the non-nuclear related sanctions on Iran to include entire sectors of the Iranian economy that aid in Iran’s ballistic missile program. It would also sanction any Iranian companies or organizations that support the missile program.
