That figure, which included pre-sales, as well as e-books and audiobooks, is a new record for Simon & Schuster, the company said.
The book, “Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man,” went on sale Tuesday and portrays President Trump in an unflattering light.
It is rare for books to sell hundreds of thousands of copies in a single week of sales — and most books will never sell that many.
“Too Much and Never Enough” will join other books about Trump that became sensational best-sellers.
The sales reflect a significant appetite for books that offer inside accounts of the Trump administration.
In some cases, Trump or his allies have sought to block unflattering books about him, which can backfire and provide an additional publicity boost to the books.
