Sen. Lindsey Graham has traveled to war zones with Sens. John McCain and Joe Lieberman while sharing tough stances with them on Iraq, Afghanistan and the war on terror.
Now, Graham, R-S.C., is breaking with his close Senate allies for the first time on a major national security issue as he rejects their calls to arm rebels trying to topple Libyan strongman Moammar Gadhafi.
"Providing arms, I'm not sure that helps us," Graham told CNN. "I don't know if you could control right now who would get the arms."
McCain, R-Ariz., and Lieberman, I-Conn., were traveling in Egypt, where they urged President Barack Obama to take tougher steps against Gadhafi.
"Now is the time for action, not just statements," Lieberman told CNN. "(We need to provide) the kinds of tangible support - no-fly zone, recognition of the revolutionary government, the citizens government, and support for them with both humanitarian assistance and I would provide them with arms."
