John Podesta reveals what he loses sleep over 'every night' — and it involves Hillary Clinton

Hillary Clinton's former campaign manager, John Podesta, spoke with CNN's Alisyn Camerota on Wednesday's airing of "New Day," and admitted that he loses sleep "every night" over President Donald Trump's win over his former client.

Discussing Trump's continued focus on Clinton and her emails — as well as his fixation on her alleged role in the Russian investigation — Podesta referred to Trump's behavior as "unprecedented" and claimed that he loses still sleep on a nightly basis over the 2016 election.

“You never saw that behavior from any other president who’s talking about the person they beat,” Podesta told Camerota. “I think it really just bugs the hell out of him that she got 3 million more votes than he did, and he keeps coming back to that. Obviously we bear the burden of having lost the Electoral College, so I lose sleep about that every night.”

About Clinton, Podesta added, "I think [Clinton has] reflected on the mistakes that she made, what she might have done different, but I think she’ll also talk [in her upcoming book] about where the country is and how to move forward.” "

"That’s what she’s always done in her life when she’s gotten knocked down," Podesta explained. "She’s tried to make a positive contribution coming out of that, and I think that that’s what this book will attempt to do."

Clinton's memoir, titled "What Happened," is set for release September 12.

The former presidential nominee wrote in the book’s introduction, “In the past, for reasons I try to explain, I’ve often felt I had to be careful in public, like I was up on a wire without a net. Now I’m letting my guard down.”

A description of Clinton's memoir released by her publisher — Simon & Schuster — said that the book “is the story of that campaign and its aftermath — both a deeply intimate account and a cautionary tale for the nation.”

It read:

"Now free from the constraints of running, Hillary takes you inside the intense personal experience of becoming the first woman nominated for president by a major party in an election marked by rage, sexism, exhilarating highs and infuriating lows, stranger-than-fiction twists, Russian interference, and an opponent who broke all the rules. This is her most personal memoir yet."
