Washington (CNN) South Carolina Republican Sen. Lindsey Graham Monday described his dinner this weekend with President Donald Trump, Fox News' Sean Hannity and conservative radio host Mark Levin as "interesting" but didn't dive into the specifics of the encounter.

"This was an interesting dinner. (First lady) Melania (Trump) was there, which means it's a good dinner," Graham told Christian Talk Radio host Josh Kimbrell on Monday. "There was Sean Hannity, Mark Levin, it was a really interesting dinner."

Graham, who also golfed with the President over the weekend, spoke on a wide range of topics Monday including the President's strategy with Iran and Supreme Court nominee Brett Kavanaugh.

"Here's I think President's Trump's views on Iran," Graham said. "That they're the cancer of the Mideast and he's going to take a different path than Obama."

Graham's remarks come after Trump threatened "severe consequences" for those who continue to trade with Iran, as administration officials said Monday that newly re-imposed US sanctions are meant to change the regime's behavior, not topple leaders in Tehran.
