New Jersey ? Gov. Jon S. Corzine’s son said his father recognized him and responded to visitors Sunday, three days after an SUV crash left him on a ventilator with a dozen broken ribs and a severely fractured leg.

“When you talk to him, he can recognize your voice, that’s my feeling,” said Joshua Corzine, the eldest of two sons. “He definitely responds when you let him know who you are.”

The governor’s three children said they were optimistic about their father’s condition.
