Now that the spin-room arguments about debate winners and losers has died down, the most enduring part of last night’s debate may be Vice President Biden’s comments on Libya. Because the administration has been so tight-lipped on the issue, Biden’s remarks are important in piecing together the puzzle of exactly what the White House knew and when.

As Jonathan noted earlier, Biden specifically contradicted the senior State Department officials and whistle blowers who just testified under oath before the House Oversight Committee earlier this week, and also took a direct swipe at the intelligence community. Josh Rogin reports on more:

Vice President Joe Biden claimed that the administration wasn’t aware of requests for more security in Libya before the Sept. 11 attacks on the U.S. mission in Benghazi during Thursday night’s debate, contradicting two State Department officials and the former head of diplomatic security in Libya.

“We weren’t told they wanted more security. We did not know they wanted more security there,” Biden said.

In fact, two security officials who worked for the State Department in Libya at the time testified Thursday that they repeatedly requested more security and two State Department officials admitted they had denied those requests.

This, along with Obama spokesperson Stephanie Cutter’s bombshell gaffe about politicizing Benghazi yesterday, means that last night’s debate probably won’t help shift the news cycle away from Libya, as the Obama campaign may have hoped. Instead, it raises even more questions for them, including: who’s telling the truth on security requests, the State Department and the security personnel on the ground or Vice President Biden?
