CNN called that big wig doc - I can never remember his name Kuptka? - and his opinion was that seizures caused from brain tumors are controlled by medication and the removal of the tumor. One senator had made a comment about people with medical problems should probably avoid situations like today, but the doc said that most likely had nothing to do with it.

I'm thinking it could just be his meds were "off" or the tumor is growing again.

In any case, he's doing well and just being kept for observation.
