The freshman senator was referring to the Sept. 11 terrorist attack against the U.S. Consulate in Benghazi that left four Americans dead, including Stevens, the U.S. ambassador to Libya.

Paul told the audience that there was a 16-person security team in Benghazi, but that the president sent them away. 

“If the president comes up here, ask him: Why in the hell did you send them home? They specifically requested to stay,” Paul said.

Republicans in Congress have been raking the administration over the coals for botching the security situation in Benghazi and have requested communications from Stevens to the State Department, in which he supposedly expressed concerns about the security situation.

“The president says the buck stops here; ask him where in the hell were the Marines? Ask him, where the hell was that 16-person security team,” Paul said.

Paul said there should have been an airplane, a DC-3, for the ambassador to use in case he was in danger but that the administration used it to transport a new electrical charging station to the Vienna embassy.

“So you have to ask yourself, is the green initiative, is the global warming campaign, more important than the security of an embassy? Greening up the Vienna Embassy,” Paul said. “We spent $100,000 for an electrical charging station to show off how green we were, but we wouldn’t have one Marine guarding our embassy, we wouldn’t allow 16 personnel to stay in Libya, we wouldn’t allow them a plane, but we’ve got enough money to make a show of a very politicized agenda by the president. 

“I think it’s inexcusable and if he says the buck stops here, someone should be fired.”

Earlier this month, Secretary of State Hillary ClintonHillary Diane Rodham ClintonGeorge HW Bush wears 'book socks' to Barbara Bush's funeral to honor her passion for literacy Obamas, Clintons to attend funeral of Barbara Bush Hillary Clinton to fundraise in DC for public charter high school MORE said she'd take responsibility for the lack of security during the attack in order "to avoid some kind of political gotcha" for the administration. The next day, in the second presidential debate, the president said that “Secretary Clinton has done an extraordinary job but she works for me.”

“I’m the president and I’m always responsible.”

Before the Senate adjourned for the November elections, Paul's bill, which would have ended all foreign aid to Libya until "they started acting like our allies," failed to pass.
