Former special counsel Robert Hur revealed in Capitol Hill testimony that Biden 'willfully' retained classified materials as a private citizen and gave them to Mark Zwonitzer - the ghost writer of his $8 million book - who later tried to destroy them. 

Hur arrived on Capitol Hill to offer insight into his devastating classified documents report that painted Biden as 'elderly' and 'forgetful' and with 'diminished faculties,' but did not recommend charges for the president.

He pushed back on Democrats who claimed his report cleared Biden of any wrongdoing, saying it 'did not exonerate' the president.

'We identified evidence that the President willfully retained classified materials after the end of his vice presidency, when he was a private citizen,' Hur said during the high-stakes hearing. 

Hur said that included in the evidence was a recorded conversation between Biden and his ghost writer Zwonitzer in which the president stated that he had just 'found all the classified stuff downstairs.'

After leaving the vice presidency, Biden and now-First Lady Jill signed a multi-book deal with Flatiron Books valued at $8 million, according to Publishers Weekly. 

The first book, 'Promise Me, Dad,' a memoir that centers on when his son Beau died and he decided not to run for president in 2015, briefly topped the best sellers list.
