Former US Presidents George and George W Bush have ripped into Donald Trump, calling him a "blowhard" who "doesn't know what it means to be President".
The comments come in a new book, The Last Republicans, about the father and son. The elder Bush was President between 1989 and 1993, while his son served from 2001 to 2009.
"I don't like him," the elder Bush told author Mark Updegrove in May 2016, after it was clear Mr Trump would secure the nomination for the Republican Party.
"I don't know much about him, but I know he's a blowhard. And I'm not too excited about him being a leader."
He didn't vote for Mr Trump, instead giving Democrat Hillary Clinton the tick. It was Ms Clinton's husband Bill who defeated Mr Bush in the 1992 election.
The younger Bush also had harsh comments for Mr Trump.
"This guy doesn't know what it means to be president."
Mr Updegrove, a historian, told CNN he agreed with the Bushes' assessment of the reality TV star-turned Commander-in-Chief.
"Donald Trump is everything that the Bush family is not. George Bush grew up thinking about the greater good. Donald Trump, I think is manifestly narcissistic."
The younger Bush didn't vote for Ms Clinton or Mr Trump, writing 'none of the above' instead.
White House press secretary Sarah Sanders said the American people voted for Mr Trump to end "decades of costly mistakes".
Ms Clinton actually received nearly 3 million more votes than Mr Trump, who ascended to the presidency thanks to the US Electoral College system.
