Jill Biden appeared to give her former president husband Joe a secret signal on The View after co-host Alyssa Farah Griffin asked a very risky question. Biden, 82, was asked about Democrat insiders saying he'd suffered a sharp cognitive decline during his final year in office and began answering the question. But after a few moments of relatively fluid speech the former president suddenly stopped and said: 'I've spoken enough.' Jill, who was sat beside her husband, picked up the answer without a beat, sparking theories she may have nudged him or kicked him under the table to shut him up.
