Robert Byrd was hospitalized late last week for a temperature spike caused by an infection, according to a statement released by Byrd's office Monday.
Byrd, a 91-year-old Democrat, entered the hospital last Friday afternoon as precautionary measure. He is "being treated with antibiotics, responding well, and is expected to be released from the hospital in a few days," according to the statement.
Byrd was first elected to the U.S. Senate in 1958.
