Ailing Sen. Johnny Isakson (R-Ga.) was released from the hospital Thursday, three days after being admitted for dehydration and a bacterial infection.

“Senator Isakson is still recovering from the bacterial infection, but his doctors felt that his condition has improved enough that he could go home and continue his recovery there,” spokeswoman Joan Kirchner said in a statement. “Senator Isakson is feeling so much better and he is glad to get back home.”

Isakson, 65, was admitted Monday to Northside Hospital in Atlanta. Dr. Steven Marlowe, one of Isakson’s attending physicians at the hospital, said the Senator’s condition has improved.

“Senator Isakson has really made great progress this week, and we are allowing him to go home today on the condition that he do nothing but rest and recover for at least the next week,” Marlowe said.
