WASHINGTON (CNN) – Sen. Robert Byrd, D-West Virginia, was released from the hospital Thursday after falling in his home two days earlier.
The 91-year-old Byrd has been hospitalized since Tuesday so that doctors could "monitor and treat a spike in his white-blood cell count, a symptom that is usually an early sign of an infection," the senator's office said in a statement.
His office also said that the senator "is looking forward to engaging in the upcoming debate and votes on health care reform – one of the most critical issues facing this Congress."
Over the next couple of days, Byrd will continue his recovery at home, his office said.
The longest serving senator in U.S. history, Byrd was first elected to the House in 1952 and was elected to the Senate in 1958.
