Charleston, W.Va. (AP) -- Sen. Robert C. Byrd, the longest-serving senator in history, is out of the hospital.
The 91-year-old West Virginia democrat was hospitalized for two days after tests uncovered an elevated white-blood cell count.
The possible infection turned up during treatment for a fall at his northern Virginia home Tuesday.
Byrd has been in frail health in recent years and was hospitalized in May and June with dangerous infections.
But he returned to the senate in July to vote and earlier this month gave his first floor speech in months, where he talked about the passing of Sen. Edward Kennedy.
Byrd's office said Thursday he will continue receiving antibiotics and recuperating at home before returning to congress for the debate on health care legislation.
