Concussion Keeps Clinton From Testifying on Benghazi We're going to take a moment now to take a turn to the other news making headlines tonight. It involves a health scare for secretary of state hillary clinton, a scare that led to a fall and a concussion. So, we want to bring in abc's david kerley in washington, following this, how is mrs. Clinton tonight? We know that she came back from her last trip nine days ago with a stomach bug, earlier in the week, she became dehydrated, fainted, have a concussion, she did not go to the hospital. Doctors are monitoring her. This means that she'll not testify this week about the attack on the mission in benghazi and the killing of our ambassador there, the republican chair of the house committee not happy about that. But abc's jake tapper has learned that john kerry will be tapped as the replacement. For hillary clinton. So, david, there's a chance she'll never testify what happened in benghazi. Two developments tonight, hillary clinton recovering from a fall and a possible secretary of state kerry in our future.
