A House committee investigating the Sept. 11, 2012, attacks on the U.S. diplomatic compound in Benghazi, Libya, spent almost 11 hours grilling Democratic presidential candidate Hillary Rodham Clinton, who was secretary of state when the attacks by Islamic militants killed Ambassador Chris Stevens and three others. By many accounts, the match ended in a draw between Clinton and Republican members in the committee, who questioned her aggressively. The investigation has lasted 17 months and has cost a reported $4.7 million. Is it time to end the probe, or is there more to be learned?
