Political analyst Mark Halperin revealed last week that former President Joe Biden’s team is prepared to release unflattering stories about their efforts to prepare former Vice President Kamala Harris for a potential run if she comes after him in her new book.

Harris announced the release of her upcoming book "107 Days," documenting her short-lived presidential run, just a week after Biden reportedly signed a $10 million deal with the Hachette Book Group for his upcoming presidential memoir.
