The Washington Post reports that Joe Biden's forthcoming memoir "Promise Me, America" reveals the warm handwritten letter Donald Trump left in the Oval Office after skipping Biden's 2021 inauguration, predicting Biden would make his mark on history. Biden calls the letter "very generous" and sees two Trumps — one writing like an old friend, one who spent weeks trying to overturn Biden's defeat — a geniality contrasting with the opponents' bitter characterizations of each other.
