Hillary Clinton acknowledges two of her biggest errors that led to her downfall in the 2016 election may have been the setup and use of a private email server while she was secretary of state and the high-dollar speeches she made to several financial firms.

In her upcoming book, Clinton concedes that it was “a mistake” to deliver high-dollar speeches to Wall Street firms following her tenure at the State Department, contributing to an out-of-touch image that dogged her throughout the 2016 presidential campaign.

“Just because many former government officials have been paid large fees to give speeches, I shouldn’t have assumed it would be okay for me to do it,” Clinton wrote, according to Bloomberg News. “Especially after the financial crisis of 2008 and 2009, I should have realized it would be bad ‘optics’ and stayed away from anything having to do with Wall Street. I didn’t. That’s on me.”

In her first on-air interview about her book that aired Sunday, Clinton also admitted that the setup and use of an unauthorized private email server while she was secretary of state also was a factor in her defeat to Donald Trump.

“The most important of the mistakes I made was using personal email,” she told CBS’s Jane Pauley.

Despite rumors that Clinton may be considering a run for mayor of New York City, or even considering another run for president, she explained in the interview that, “As an active politician it’s over. I am done with being a candidate.”

However, being “done” as a candidate doesn’t mean the former senator and secretary of state is done with politics. She noted that other presidential losers like Mitt Romney, Al Gore, and John Kerry have stayed influential in the political discussion through the years after their defeats.

While Clinton’s book will draw out the mistakes she feels she made personally, there will also be blame to pass around. The book will lay out a scolding of then-FBI Director James Comey, and his decision to resume the email investigation in late October.

The memoir “What Happened” is slated for release later this week.
