Ahhh. So you have nothing to back up your claim, then.
Nevertheless, as is most often the case, reality disagrees with leftists.
Clinton took responsibility for Libya before the debate.
On the eve of the second presidential debate, Secretary of State Hillary Rodham Clinton said Monday night that she took responsibility for the failure to successfully defend against the Sept. 11 attack on the United States diplomatic compound in Benghazi, Libya.
Now do you have a quote from the debate where Obama took responsibility, or not?
If not, perhaps you should stop claiming he did.
