WASHINGTON (AP) Mitch McConnell said after the 2020 election that then-President Donald Trump was stupid as well as being ill-tempered, a despicable human being and a narcissist, according to excerpts from a new biography of the Senate Republican leader that will be released this month.

McConnell made the remarks in private as part of a series of personal oral histories that he made available to Michael Tackett, deputy Washington bureau chief of The Associated Press.

Tacketts book, The Price of Power, draws from almost three decades of McConnells recorded diaries and from years of interviews with the normally reticent Kentucky Republican.

The animosity between Trump and McConnell is well known Trump once called McConnell a dour, sullen, and unsmiling political hack .

But McConnells private comments are by far his most brutal assessment of the former president and could be seized on by Democrats before the Nov. 5 election. The biography will be released Oct. 29, one week before Election Day that will decide if Trump returns to the White House.
