Q&A: A look at Clinton, Benghazi, House investigation

WASHINGTON (AP) — The deadly 2012 attack on a U.S. compound in Benghazi, Libya, moves to the forefront of the presidential race when Democratic front-runner Hillary Rodham Clinton testifies Thursday before a Republican-led House committee.
Republicans say the investigation is focused on the four Americans, including Ambassador Chris Stevens, killed in the Sept. 11, 2012 assault. Democrats and a few Republicans say the probe, which has spent at least $4.5 million so far, is focused on Clinton and has undermined her White House bid.
