It was a scary moment but he appears to be fine:
Update at 10:47 a.m. ET: USA TODAY’s Tom Vanden Brook says aides and others in the audience rushed to Petraeus’ side. He regained consciousness and walked from the hearing room under his own power and the hearing was abruptly adjourned.
Vanden Brook quotes Sen. Carl Levin, the Michigan Democrat who chairs the committee, as saying the general “appears to be doing very much better.”
Petraeus was eating, Levin says, and may have been dehydrated. Levin says the hearing might resume. Senators remain in the chamber.
Imagine having to listen to politicians drone on like that while you’re already dehydrated and exhausted. I’m surprised that the general is already up and walking.
