Hillary Clinton's book called "What Happened" hits bookstore shelves today, and she's talking about it.

FOX's Tonya J. Powers has the story:

Hillary Clinton says she is convinced that Donald Trump had help from the Russians in the 2016 presidential election.

In an interview with USA Today, she says she believes there was communications between the President's associates and Russian officials and that they tried hard to hide it.

She also believes Russian president Vladimir Putin wanted her to lose.

As for former FBI Director James Comey, she believes his last minute announcement about her emails 11 days before the election cost her momentum and that she wanted to hit back hard, but her team convinced her to let it go and move on.

She says she believes that was a mistake.
