Trump reportedly said Hitler 'did a lot of good things': new book
The exchange is recounted in the upcoming book, "Frankly, We Did Win This Election," by Michael Bender of The Wall Street Journal, the British newspaper said.
The Guardian said it had obtained a copy of the book ahead of its publication next week.
According to the book, Kelly had "reminded the president which countries were on which side during the conflict" and "connected the dots from the first world war to the second world war and all of Hitler's atrocities."
"Kelly pushed back again," the Guardian quoted Bender as writing, "and argued that the German people would have been better off poor than subjected to the Nazi genocide."
Kelly, a former Marine Corps general who left the White House in early 2019, has made a number of critical comments about Trump following the January 6 attack on the US Capitol by supporters of the former president.
