President Obama has named U.N. Ambassador Susan Rice—a central figure in the Benghazi scandal—as the new national-security adviser. Rice will replace Tom Donilon, who resigned Wednesday morning, as the head of the National Security Council. "I am absolutely thrilled that she’ll be back at my side leading my national-security team in my second term," Obama told reporters. Rice had been rumored to become the next secretary of State, but Republicans vowed to block her nomination. Now it appears the White House is getting the last laugh, since the national-security adviser does not need Senate confirmation.
