BOSTON -- Massachusetts U.S. Sen. Ted Kennedy is on his way to Washington after spending months in treatment for brain cancer at his Hyannisport home.

Kennedy's office said Tuesday the senior senator will head to the nation's capital to spend time at his residence there because he has not been there in months and believes it's a good time to visit.

His aides said Kennedy will remain in Washington until Thanksgiving when he will return to Cape Cod to celebrate the holiday.

It was unclear whether Kennedy will visit Capitol Hill while in Washington. They said he will continue to work from his district home on the Democratic agenda, particularly his health care bill.
