WASHINGTON (AP) — Hillary Rodham Clinton says many unanswered questions remain about the deadly 2012 terrorist attack in Benghazi, Libya, even as U.S. authorities have captured their first suspect in the case.

Clinton, speaking in separate interviews with CNN and Fox News, said Tuesday she was still seeking information on the attacks that killed U.S. Ambassador Chris Stevens and three other Americans and led to numerous investigations. But she defended the Obama administration’s response to the incident and said the State Department tried to respond to the fast-moving attacks that have become a focal point of criticism from Republicans.
