'We've Got to Enforce the Law': ICE Director Lays Out Hard Line on Illegal Immigration

Senator John McCain (R-Ariz.), still recovering from a surgery during which he was discovered to have cancer, was in good spirits in Washington Thursday, riffing on his colleagues.

McCain was speaking on Capitol Hill with Sens. Lindsey Graham (R-S.C.) and Ron Johnson (R-Wis.) about how he cannot support the current Senate ObamaCare repeal legislation.

He said his decision is "largely guided" by the advice of his state's Republican governor, Doug Ducey, who McCain said is concerned about its effects on the Grand Canyon State.

"I trust my governor," McCain said of Ducey.

During the speech, Graham's phone began ringing loudly, and McCain turned to tell the assembled press they were "about to hear from an antique phone."

Graham stepped away to check his flip phone, as McCain joked that no one in America still has one like it, but maybe "somewhere in Togo."

Resuming his speech, McCain continued to voice his concern over the health care legislation when Sen. Bill Cassidy (R-La.) appeared.

McCain said freshmen like Cassidy never seem to be on time for events.
