Sen. John McCain (R-AZ) says that Senate Majority Leader Harry Reid (D-NV) is accusing Republicans of politicizing an attack on the U.S. diplomatic facilities in Benghazi because he probably "doesn't care" about the death of U.S. ambassador Christopher Stevens.

McCain told CNN's Candy Crowley on Sunday that the Obama administration had taken it's time to acknowledge the attack in Libya -- which resulted in the death of Stevens and three American staffers -- was terrorism because of "willful ignorance or abysmal lack of knowledge of the facts."

Crowley pointed out that Reid had recently asserted that it was "sad and disappointing" that some Republicans were using the attack to "score cheap political points" by calling for the resignation of U.S. Ambassador to the United Nations Susan Rice.

"Maybe Sen. Reid doesn't care about Christopher Stevens," McCain charged. "Maybe he doesn't care about those three other brave Americans. We do."

"You know he does though, right?" Crowley asked.

"No," McCain insisted. "Well, to make a statement like that, of course, then politicizes an issue that all Americans should be concerned about what information there was and what caused his death, every American -- no matter whether they're Democrat or Republican. So, he's the one that's taken the cheap political shot."
