Outgoing Secretary of State HILLARY CLINTON probed on Capitol Hill “cover-up” allegations on the deadly Sept. 11th raid in Benghazi, Libya.

In a packed hearing room, Clinton answered tough questions from Republicans, offering a detailed timeline of events on Sept. 11 and the administration efforts to aid the Americans in Libya while simultaneously dealing with protests in Cairo and countries in a state of violent unrest.

Clinton insisted the department is moving swiftly and aggressively to strengthen security at U.S. missions worldwide as she testified.

Clinton once again took full responsibility for the department's failure to act on intelligence that might have prevented the attack on the U.S. Consulate in Benghazi, Libya killing Ambassador Chris Stevens and three other Americans.

Her voice cracking at times, Clinton said the work was highly personal.

"I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews. I put my arms around the mothers and fathers, sisters and brothers, sons and daughters," Clinton said, her voice cracking.

She also took House Republicans to task for recently stripping $1 billion in security aid from the hurricane relief bill.

Clinton was the sole witness at back-to-back hearings before the Senate and House foreign policy panels on the September raid.

Her testimony focused not only on the attack but the growing threat from extremists in northern Africa like Algeria and Mali, pointing out that Libya was not an isolated incident.

"The Arab revolutions have scrambled power dynamics and shattered security forces across the region," she said.

"And instability in Mali has created an expanding safe haven for terrorists who look to extend their influence and plot further attacks of the kind we saw just last week in Algeria."

Clinton’s appearance had been delayed due to her shocking brain crisis and hospitalization as The ENQUIRER previously reported.

It is hoped that Clinton will put to rest claims as those voiced by the newest member of Senate Foreign Relations Committee, Sen. John McCain, R-Ariz, who charged, “It's been a cover-up from the beginning.”
