WASHINGTON (AP) — Secretary of State Hillary Clinton, sidelined for almost a month by a string of medical problems, is upbeat and planning to return to work next week, the State Department said Thursday.

One day after being released from the New York hospital that was treating a blood clot in her head, Clinton was at home resting, but was far from idle. She spent the day engaging with senior staff, reviewing paperwork and calling in to a meeting of her foreign policy advisory board, said her spokeswoman, Victoria Nuland.

"She's looking forward to getting back to the office," Nuland said. "She is very much planning to do so next week."
