WASHINGTON - Secretary of State Hillary Rodham Clinton has been released from a New York hospital where she was treated for a blood clot in her head.

Clinton spokesman Philippe Reines said her doctors advised her that she has been making progress on all fronts and are confident she will make a full recovery.

He said Clinton, 65, is appreciative of the excellent care she received at New York-Presbyterian Hospital and is eager to get back to work. A date for her return to the State Department has not been set.

Clinton had been in the hospital since Sunday, where she was being treated with blood thinners to dissolve the clot. Doctors discovered the clot during a follow-up exam stemming from a concussion she suffered earlier in December.
