A day after she was discharged from hospital, Secretary of State Hillary Rodham Clinton was planning to return to work next week, spokeswoman Victoria Nuland said Thursday.
Staff who have spoken to her say she is "sounding terrific, upbeat, raring to go," Nuland told reporters.
Clinton, 65, has been in a New York hospital since the weekend for treatment of a blood clot between her brain and skull. Blood thinners were administered, her physicians said.
Clinton, who plans to leave office when US President Barack Obama is inaugurated for his second term on January 20, suffered a concussion in mid December after a fall. The blood clot was discovered during a routine checkup. Her fall was attributed to weakness from a stomach virus and dehydration.
Nuland said the secretary of state was resting at home in New York and was "looking forward to getting back to the office" next week. She was talking to staff and receiving documents at home. Nuland described the flood of good will messages from around the world as a "tsunami."
The clot in Clinton's head was located in a large vein that drains blood from the brain. Left untreated, the condition could have caused pressure to build on the brain and led to a stroke, experts said.
Clinton's doctors have advised her not to do any international travel "for a little bit," Nuland noted.
Nuland said that Clinton is "committed" to testifying in Congress about the September 11 attack on the US consulate in Benghazi, Libya, where the ambassador and three other Americans were killed. Clinton's previous scheduled testimony was cancelled due to her accident, and Nuland said staff was trying to arrange new dates with the committees.
A Senate committee on Monday released a report faulting the State Department for failing to adequately respond to mounting security threats ahead of the assault.
Obama has nominated Senator John Kerry, chairman of the Senate foreign relations committee, to replace Clinton at state. Some senators want to hear her Benghazi testimony before they proceed with confirmation hearings for Kerry, but Nuland said she knew of no such link between the two proceedings.
"We are eager for both to happen as soon as appropriate and as soon as the committee is ready," Nuland said.
Kerry has been preparing for the hearings at the State Department in a standard procedure to get new secretaries ready for confirmation, Nuland said. "He had a number of meetings with senior staff, has received a huge file of briefing materials," she said.
