Sen. Edward Kennedy is said to have had "a restful night's sleep" after brain surgery and is recovering with no complications.

In a statement issued to The Associated Press on Tuesday, aides to the Massachusetts Democrat said, "He is experiencing no complications, and has been walking the hallways, spending time with family and actively keeping up with the news of the day."

Kennedy is expected to leave Duke University Medical Center in Durham next week.

The 76-year-old Kennedy was diagnosed with a malignant glioma in the left parietal lobe of his brain after suffering a seizure on May 17 at his home in Hyannis Port, Massachusetts.

He underwent more than three hours of surgery Monday, during which doctors sliced away at the tumor.

A spokesman said that when Kennedy emerged, he told his wife that he felt "like a million bucks."

"Sen. Kennedy was awake during the resection, and should therefore experience no permanent neurological effects from the surgery," Kennedy surgeon Dr. Allan Friedman said in a statement. "The surgery is just the first step in Senator Kennedy's treatment plan. I hope that everyone will join us in praying for Senator Kennedy to have an uneventful and robust recovery."

The plan now is for the senator to remain in North Carolina for about a week. He'll receive drugs to prevent brain swelling or seizures.

Kennedy will also be closely monitored for possible bleeding and blood clots that could cause a stroke.

Kennedy's surgeon said the senator will undergo targeted radiation at Massachusetts General Hospital in Boston, along with chemotherapy treatment.
