He made the comment via Twitter after having dinner last night with Trump:
Pres @realDonaldTrump is NOT going to let the nutjob in North Korea develop a missile - with a nuclear weapon on top - that can hit the US.— Lindsey Graham (@LindseyGrahamSC) April 25, 2017
In a Fox News interview this morning, Graham said he preferred to curb North Korean aggression through diplomacy, "using China" to stop North Korea from trying to develop intercontinental ballistic missiles. Graham said he sees military force as a "last resort."
"[Trump] doesn't want a war any more than I do, but he's not going to let them get a missile. That's where they're headed. And China needs to up their game to stop this before it gets too late," Graham told Fox.
Graham and the other top Senate war hawk, Sen. John McCain attended the dinner with Trump.
