Biden: 'My memory is fine' - what's just changed for the presidential election?

Joe Biden couldn't remember when he was vice president, according to a new report.

And, according to the same investigation, he couldn't remember when his son died.

Then, when trying to reassure everyone about the claims about his memory, he confused the presidents of Mexico and Egypt.

Not ideal for someone who wants to run for president - and even worse for someone already doing the job.

So what has the speculation done for his election chances this year - and for those of his rival, Donald Trump?

Yalda Hakim presents this Sky News Daily with political strategist Hilary Rosen and pollster Scarlett Maguire.
