Two separate groups of Senators sent letters Friday afternoon seeking information about the protections in effect in Benghazi.
Sens. Barbara Mikulski (D-Md.), Dan Coats (R-Ind.), Bill Nelson (D-Fla.) and Roy Blunt (R-Mo.) wrote to Secretary of State Hillary Rodham Clinton questioning the effectiveness of host-country security at the perimeter of embassies and consulates.
"While we laud reports that many Libyan security staff bravely fought to protect U.S. personnel in Benghazi, the incident raises the broader question of the adequacy of indigenous security forces in providing perimeter security, particularly in conflict and transitional countries," they wrote.
Senate Homeland Security and Governmental Affairs Chairman Joe Lieberman (I-Conn.) and ranking member Susan Collins (R-Maine) sought a security audit from the State Department's inspector general.
Aides to President Barack Obama told reporters traveling with the president to Ohio that he continued to follow the developments in the Middle East, even as he made campaign trips.
"We're still learning about them now. Obviously, the president's priority is on working with his team ... to gather more information, to make sure that the diplomats serving overseas are safe. And that is his priority," campaign spokeswoman Jen Psaki said. "And he can do that, fortunately, because of what's provided on Air Force One and the accessibility of people while he's out there campaigning as well, and that's what he'll continue to do."
