Reid: 'Infirm' Bob Dole hospitalized at Walter Reed

"We should do this to recognize what a great leader Bob Dole is," Reid said.

The top Senate Democrat added he saw the former Republican leader as "a stalwart figure in the history of America."

"He had all the qualities of a leader that I admire and certainly would wish I had," Reid said.

Dole, who was the 1996 Republican presidential nominee and the 1976 vice presidential nominee, has been plagued by a leg infection for years and spent more than three years in the hospital after being wounded during World War II. 

But in a statement to CBS News, an assistant for Dole said he had been hospitalized for a "routine" procedure.

"He checked himself in for a routine procedure and will discharge tomorrow," Dole's assistant said. "Doing well and watching the CRPD debate on CSPAN 2."

The former Republican leader served on the panel convened by former President George W. Bush to investigate problems at the Army medical center after substandard conditions were revealed in a Washington Post investigation in 2007.
