LIMA, Peru – U.S. Secretary of State Hillary Rodham Clinton is taking responsibility for security at the U.S. consulate in Libya where an attack last month killed the U.S. ambassador and three other Americans.

Pushing back against Republican criticism of the Obama administration for its handling of the situation, Clinton said Monday in Lima, Peru, that security at all of America’s diplomatic missions abroad is her job, not that of the White House.

There are three investigations into the attack going on now: an FBI probe into the deaths of the four Americans, an independent inquiry by a panel appointed by Clinton, and congressional hearings.

In television interviews, Clinton said she is responsible for State Department security. She told Fox News that “the decisions about security are made by security professionals.”

“I take responsibility,” she told CNN. “I’m in charge of the State Department’s 60,000-plus people all over the world (at) 275 posts. The president and the vice president wouldn’t be knowledgeable about specific decisions that are made by security professionals. They’re the ones who weigh all of the threats and the risks and the needs and make a considered decision.”
