Graham jokes on Twitter about tipping off Syrian government to McCain's visit

Asked on Twitter if he had been forewarned, Graham said: “No, if he had I would have called the Syrians.” He added “(j/k)” for just kidding at the end of his tweet.

Graham made a similar joke on Monday, when news of McCain's trip first became public. 

“Best wishes to @SenJohnMcCain in Syria today,” Graham tweeted Monday. “If he doesn't make it back calling dibs on his office.”

The two hawkish senators are very close and have long jointly called for the Obama administration to play a more forceful role in Syria, by arming vetted rebel groups and enforcing a no-fly zone. McCain slipped into rebel-controlled Syrian territory on Monday along with a rebel leader.

The administration has balked at getting more involved in the conflict, out of concern that it could inflame the region and that weapons could end up in the hands of Islamist militants. Congress, however, has run out of patience as the death toll tops 70,000; last week a key Senate panel voted overwhelmingly for a bipartisan bill to arm the rebels.
