McCain last week came out against health-care legislation from Graham and Cassidy that would repeal major parts of ObamaCare, saying he wants a bipartisan bill to go through the normal committee process. That's the same reason he gave when he helped defeat the ObamaCare repeal bill over the summer.

"To any American who has a problem with John McCain’s vote, all I can tell you is John McCain was willing to die for this country, and he can vote any way he wants to, and it doesn't matter to me," Graham said of his close friend.

Graham’s comments were applauded by the other three senators.
