was running for president in june. his wife attended that without him. and jenna bush tweeted eded out thanks for the thoughts and prayers for her grandfather. >> we want to bring in cnn's chief medical correspondent, son jay gupta sanjay gupta. a broken bone in his neck that still sounds seriously? >> there are several bones in the neck. what i've read is that the vertebrae, which is one of the bones in the front of the neck is broken. the big question did he have any weakness or numbness in his hands as a result? did that bone push on his spinal cord? from what i've read it doesn't sound like that happened.
