MCCAIN CHALLENGES OBAMA ON NATIONAL SECURITY CREDENTIALS

While speaking to the NRA in Louisville, Kentucky, the presumptive GOP nominee responds to Obama calling him "naive" and "irresponsible" on Iran, says "he should know better." "I have some news for Senator Obama: Talking, not even with soaring rhetoric, in unconditional meetings with the man who calls Israel a ‘stinking corpse’ and arms terrorist who kill Americans will not convince Iran to give up its nuclear program." "...the American people have every reason to doubt whether he has the strength, judgment and determination to keep us safe." Read his remarks here. Watch video above. Obama camp responds: "No amount of utterly predictable fear-mongering and tough talk can change the fact that John McCain is running to continue the most disastrous foreign policy in recent American history.” Full statement here.
