Sarah Huckabee Sanders: Hillary Clinton "Propping up Book Sales With False and Reckless Attacks"

The White House press secretary said she's "not sure" if Donald Trump will read Clinton's book.

When a White House reporter asked press secretary Sarah Huckabee Sanders about Hillary Clinton's new book in a briefing Tuesday afternoon, she was prepared.

"I think it's sad that after Hillary Clinton ran one of the most negative campaigns in history and lost, the last chapter of her public life is going to be defined by propping up book sales with false and reckless attacks," Sanders said, looking down at her notes while speaking.

Sanders said she is "not sure" if Donald Trump will read the book, What Happened, which was released Tuesday and is being promoted heavily by Clinton in appearances on television and book signings, including one in New York City that attracted big crowds. (On Wednesday, Clinton is scheduled to discuss the book on both Today and The View.)

"I would think that he’s pretty well versed on what happened, and I think it’s pretty clear to all of America," Sanders said, making a dig at the title of the book.

Despite the White House's criticism, Clinton's book — a tell-all about her failed campaign and how she sees her role going forward — is already selling well, hitting No. 1 on Amazon's best-sellers list.
