Obama, Romney battle over Libya

It looks like the political battle over Libya will last at least through Election Day.

Vice President Biden and Republican veep nominee Paul Ryan took up the issue Wednesday, a day after President Obama and GOP rival Mitt Romney argued about the confusing aftermath of the Sept. 11 attack in Benghazi that killed U.S. Ambassador Christopher Stevens and three other Americans.

On ABC's Good Morning America, Biden accused the Romney campaign of seeking to "politicize" a tragedy, "and their strategy seems to be to try make it appear that the president didn't care or didn't know or was lying."

Ryan, also on ABC, said: "What is troubling about this is as we learn more these facts just don't add up."

Romney got caught short during the debate when he said Obama did not describe the attack as terrorism for weeks afterward.

In fact, on Sept. 12, the day after the attack, Obama said: "No acts of terror will ever shake the resolve of this great nation, alter that character, or eclipse the light of the values that we stand for."

Ryan called that "a passing comment about acts of terror in general, it was not a claim that this was the result of a terrorist attack." Instead, he noted, officials spent days attributing the attack to a protest over an anti-Islam video that turned violent -- only to see the State Department say later there was never any protest.

Said Ryan: "Why send (U.N. Ambassador) Susan Rice out four days later to say this was the result of a spontaneous mob reacting to a YouTube video? Why go on The View? Why go on these other shows and not say the same thing?"

Obama and aides said the explanations shifted as the evidence did, and have vowed to track down the perpetrators of the Benghazi attack.

During the debate, Obama told Romney: "The suggestion that ... anybody on my team would play politics or mislead when we've lost four of our own, governor, is offensive. That's not what we do. That's not what I do as president. That's not what I do as commander in chief."

Look for the political battle to continue Monday during the third and final Obama-Romney debate.
