Former Senate Majority Leader Bob Dole (R-Kan.), 87, is back in Walter Reed Army Medical Center Saturday after being in and out of the hospital earlier this week.

Dole said in a statement released by Alston & Bird, the law firm where he serves as special counsel, “I was examined, treated and discharged Friday when everything looked clear, After a recurrence of a fever I decided to stop by the George Washington University Hospital nearby then return to Walter Reed Friday evening for further examination.”

In the written statement obtained by CNN, Dole said he had been admitted to Walter Reed on Tuesday because of the initial fever.

“Overall I feel good today and I am grateful for the tremendous care I have received and continue to receive at Walter Reed Army Medical Center,” he said.

Dole spent about 10 months last year at Walter Reed recuperating from knee surgery.
