Sources close to Biden report 'marked incidence of cognitive decline' in last 6 months: Bernstein

Anonymous sources reportedly close to President Biden have allegedly witnessed "15, 20 occasions in the last year and a half" similar to what the country saw at last week's presidential debate. 

"These are people, several of them who are very close to President Biden who loved him, have supported him and among them are some people who would raise a lot of money for him. And they are adamant that what we saw the other night, the Joe Biden we saw, is not a one-off, that there have been 15, 20 occasions in the last year and a half when the president has appeared somewhat as he did in that horror show that we witnessed," CNN's Carl Bernstein told Anderson Cooper Monday night, referring to the debate. 

"And what's so significant is the people that this is coming from, and also how many people around the president are aware of such incidents, including some reporters incidentally who have witnessed some of them," said the famed reporter, who rose to prominence in helping expose the Watergate scandal at the Washington Post.
