Former Senate Majority Leader Bob Dole is

hospitalized at Walter Reed Army Medical Center, undergoing therapy

after recovering from pneumonia, his spokesman says.

Dole, 86, was admitted to the military hospital about three

weeks ago with a respiratory condition, spokesman Michael Marshall

said Monday. Dole recuperated from his bout with pneumonia but has

remained at Walter Reed to regain strength from earlier surgery on

his left knee, Marshall said.

Dole overcame disabling war wounds to forge a 36-year political

career. In the early 1990s, he underwent successful surgery for

prostate cancer.

He served four terms in the House before he was elected to the

Senate in 1968. He retired from the Senate in 1996 to run for

president against Democrat Bill Clinton.
