Right, sorry, it was his wife that outed him for having Hitler speeches book "My New Order" back in 1990, which he apparently kept in a cabinet next to his bed. In the interview he also admitted having a copy of Mein Kampf, though he never openly claimed to read that book often. When he quoted Hitler in 2023 he said it was just a coincidence. Which caused no one to feel uneasy, no one at all. His former chief of staff claimed that Trump praised Hitler for doing some good things, like rebuilding the economy.

So right, sorry, I mixed the "Mein Kampf" for "My New Order", and it was his wife that outed that, he only confirmed.
