Clinton concussed after collapsing at home
WASHINGTON // Secretary of State Hillary Clinton, who skipped a trip to the UAE this past week because of a stomach virus, has sustained a concussion after fainting, the State Department said.
Ms Clinton, 65, who is expected to leave her job soon, was recovering at home after the incident last week and is being monitored by doctors, according to a statement by aide Philippe Reines.
Dr Lisa Bardack of the Mt Kisco Medical Group and Dr Gigi El-Bayoumi of George Washington University said that Ms Clinton was suffering from a stomach virus and fainted after becoming extremely dehydrated. The doctors said they recommended that Ms Clinton continue to rest and avoid strenuous activity and cancel all work events for the next week.
Ms Clinton was diagnosed with a concussion on Thursday after fainting at home earlier this week, according to a State Department official who spoke on the condition of anonymity because he was not authorised to discuss Ms Clinton's injury publicly. The doctors did not determine it to be a "severe" concussion, the official said.
President Barack Obama telephoned his top diplomat on Saturday to wish her well, a White House official said.
The State Department said in a statement that Ms Clinton will continue to work from home in the week ahead and looks forward to returning to the office "soon".
The Senate Foreign Relations Committee said it will not hear from Ms Clinton as planned at a hearing on Thursday into the September 11 attack against a US diplomatic outpost in Benghazi, Libya, that killed four Americans, including the US ambassador. The House Foreign Affairs Committee also said Ms Clinton would no longer give scheduled testimony at its hearing on Thursday on Libya.
Senior State Department officials William Burns and Thomas Nides are to take Ms Clinton's place at both hearings.
Ms Clinton's aides on Saturday informed the Senate committee chairman, John Kerry, about her health, and the Massachusetts Democrat "insisted that given her condition, she could not and should not appear" as planned, said Mr Kerry's spokeswoman Jodi Seth. Mr Obama is expected to nominate Mr Kerry to succeed Ms Clinton.
