Sen. Robert Byrd (D-W.Va.) has been released from the hospital Tuesday after a six-and-a-half-week stay, according to a statement released by his office.

Byrd “is resting comfortably at home, where he will continue his recuperation and physical therapy,— the brief statement said.

“I am pleased to be home in anticipation of celebrating our Nation’s birthday with my loving family,— Byrd, 91, said in the release. “I also thank everyone who sent me their good wishes and prayers.—

Byrd was first admitted to the hospital on May 15 for what was then described as a mild infection. His office later said that Byrd had developed a staph infection.

Few other details about the Senator’s condition have been made available. Byrd’s office repeatedly declined to say where the Senator was being treated, and Tuesday’s statement did not indicate when Byrd is expected to return to work.

The Senate’s longest-serving Member has been admitted to the hospital a few times over the past year, including last June for a minor infection. Byrd also serves as President Pro Tempore, a position that puts him third in the presidential line of succession.
