Republicans have accused the Obama administration of stonewalling congressional investigators and misleading the public about the nature of the attack in the weeks before the presidential election. Republicans have questioned Clinton's response to the attacks and whether she could have done more to secure the diplomatic compounds.
Multiple independent, bipartisan and Republican-led investigations have faulted the State Department for inadequate security in Benghazi, leading to four demotions. No attacker has been arrested.
In her book, Clinton calls the accusations plainly political, writing that she will not be "part of a political slugfest on the backs of dead Americans."
Asked whether she will testify before a new congressional committee investigating the attacks, Clinton would not make any commitments, saying it depends on how the inquiry is conducted.
"I'm not going to say one way or another," Clinton said. "We'll see what they decide to do, how they conduct themselves: Whether this is one more travesty about the loss of four Americans or whether this is in the best tradition of the Congress, an effort to try and figure out what we can do better."
