The 44th US President is alleged to have found Joe Biden, his deputy at the time so “condescending” he asked an aide: “Shoot. Me. Now.”
A new book, entitled 'The Long Alliance: The Imperfect Union of Joe Biden and Barack Obama', which is out on September 13, appears to suggest there was a lot of tension in the relationship between the two men.
The book also alleges that in 2020, Mr Obama was reluctant in his backing for Mr Biden's bid to become US President, initially believing his candidacy would be “unthinkably painful.”
