'His stability is in question': Biden hits Trump for claiming Harris ousted him in 'coup'

Joe Biden took a shot at Donald Trump's "stability" after the Republican presidential nominee claimed the Democratic president was the victim of a "coup."

During preparations for his Democratic National Convention speech on Monday, CNN host Kaitlan Collins asked Biden to respond to Trump's claim that Vice President Kamala Harris ousted him in a coup.

"Donald Trump claims that you were pushed out from the top of the ticket, and this amounts to a coup from your party," Collins told Biden. "What do you make of those claims?"

"His stability is in question," Biden replied, according to Collins.

"He said he was feeling good about his speech," Collins explained.
