Hillary Clinton book to contain 'bombshell,' focusing on Russia and Comey

With Hillary Clinton supporters anxiously anticipating her upcoming tell-all, we're learning more about the book due out in September.

According to the Hill, Clinton will double down on her theory that Russia's election meddling and James Comey's public remarks over her email investigation ultimately cost her the election.

A longtime ally revealed, "[Clinton] wants the whole story out there from her own perspective. I think a lot of people are going to be really surprised by how much she reveals."

According to the ally Clinton's upcoming book is set to be a "bombshell."

Clinton's long-held assertions on what cost her the election run counter to recent musings from Democratic Senate Minority Leader Chuck Schumer.

Schumer told the Washington Post, "When you lose to somebody who has 40 percent popularity, you don't blame other things — Comey, Russia — you blame yourself. People didn't know what we stood for, just that we were against Trump."

But one adviser said recent reports of Russia's involvement have left Clinton feeling "validated."

Clinton will also reportedly focus on how sexism and misogyny affected her campaign.

Meanwhile, President Bill Clinton may have a project of his own in the works. Deadline is reporting Clinton and writing partner James Patterson of the upcoming thriller novel "The President is Missing" are in talks for a potential movie or tv deal.
