Biden clearly had problems earlier, but 1) some people didn't want to jump the gun and pass a judgement that could be seen as being premature and politically motivated, 2) Biden had his physical this month so his mental state is particularly relevant now, and 3) Brit Hume isn't on TV that much now, he probably wasn't asked about this earlier, and on those other occasion she may have had other things to say that were more important at the time.
