Hillary Clinton's preemptive strike.
The former U.S. Secretary of State is taking on critics who continue to question her role in the 2011 attack on the U.S. consulate in Benghazi.
In a chapter of her upcoming book obtained by Politico, Clinton accuses Republicans of exploiting the tragedy.
She writes in part, "I will not be a part of a political slugfest on the backs of dead Americans. It's just plain wrong, and it's unworthy of our great country."
