The sales total of Obama’s memoir, “Becoming,” which was released Tuesday, includes all formats and editions, including as an audio book and Spanish-language version, according to Penguin Random House.

The sales number puts the former first lady’s book on par with “Fear: Trump in the White House,” by veteran journalist Bob Woodward. The reporter's book sold 750,000 copies in one day when it hit shelves in September.

“We are thrilled by the extraordinary response to Mrs. Obama’s beautifully rendered and deeply personal memoir, and we are confident that ‘Becoming’ will inspire millions of readers,” Penguin Random House U.S. CEO Madeline McIntosh said in a Friday statement.

It’s been a banner year for books both about and authored by political figures. A September report from market research company NPD Group found that political book sales were up 25 percent in 2018.
