Jodi Kantor, the author of a new book on the Obamas, on Sunday pushed back against any suggestion that she had tried to portray Michelle ObamaMichelle LeVaughn Robinson ObamaCriticism of Melania Trump shows a lot about the #MeToo movement Obama tells Letterman of showing off his 'dad moves' in front of Prince Smithsonian to unveil Obamas' portraits next month MORE as an "angry black woman."

“Those words aren’t in the book. There’s nothing that implies that she is,” Kantor, whose book has come under strong criticism from the White House, said on CBS’s “Face the Nation.”

“She is portrayed as a very strong woman.”

Some commentators have said that the White House is taking its criticism of the book, which contains some very flattering descriptions of the First Family, too far.

Earlier in the week, the First Lady herself pushed back against the new book.

“That’s been an image that people have tried to paint of me since the day Barack announced – that I’m some angry black woman,” Michelle Obama told CBS News.

But Kantor said Sunday that the “twist” of her book was that Michelle Obama may be handling the pressures of Washington better than the president.

“Because he came to Washington on the top of the Earth, and has kind of been descending to Earth ever since,” the author said. “And Mrs. Obama came here with low expectations and exceeded them.”
