'America's Got Talent' Winner Michael Grimm Makes Miraculous Recovery from Mystery Illness

Michael Grimm, winner of "America's Got Talent" season 5, is making progress in his recovery after being hospitalized with a mysterious illness. He can now speak and walk on his own, although he still needs to relearn movement and speech. Doctors have been unable to diagnose a specific disease or syndrome, and Michael's wife says he had an adverse reaction to being on a ventilator. While he is no longer using a cane, he still can't sing or play guitar. Michael's hospital bills have exceeded $200,000, but fellow Las Vegas performers are organizing a benefit concert to help cover the costs.
