Sen. Byrd Back In Hospital

Ninety-one-year-old Sen. Robert C. Byrd of West Virginia has been hospitalized with what his office says is a spike in temperature.

In a statement, Byrd's office says he was hospitalized late Friday, is being treated with antibiotics and is expected to be released in a few days.

The statement says that according to doctors, the temperature spike was caused by a minor infection.

CBS News' Bob Fuss reports that "Byrd has served in Congress for more than half a century and is president pro-tem of the Senate - third in line in the presidential succession."

The aging senator has allegedly been slowing down of late and recently stepped down as chairman of the powerful Senate appropriations committee.
