Hillary Clinton suffers concussion - Telegraph The State Department gave no details of her illness but CNN reported that several members of her staff had also fallen ill with the stomach virus. Mrs Clinton had been due to appear before a Congressional committee on Thursday to testify on the attack on the US consulate in Benghazi, which killed four Americans, including the ambassador to Libya. "While suffering from a stomach virus, Secretary Clinton became dehydrated and fainted, sustaining a concussion," the spokesman said. She has been recovering at home and will continue to be monitored regularly by her doctors. At their recommendation, she will continue to work from home next week, staying in regular contact with Department and other officials. She is looking forward to being back in the office soon.
