Details: Graham told me in a phone interview:

“This is worse than when Obama left Iraq, because you’ve got so much information as to what happens. This would be a game changer to our national security. This would pave the way to the re-emergence of ISIS.”

“If I hear the president say one more time, ‘I made a campaign promise to get out of Syria,’ I’m going to throw up.”

“He took an oath of office to protect the nation against all enemies, foreign and domestic. There’s no bigger enemy to our nation than ISIS. And there’s no way we can protect the country from radical Islam without partners like the Kurds.”

“His duty as commander-in-chief, I believe, compels him to act honorably by the Kurds, and it is impossible for Turkey to go into Syria and not create a devastating ripple effect, no matter what the president says to [Turkish President Recep Tayyip] Erdogan.”
