"It was a very painful period. Again, my whole life has been dedicated to institutions that work not to have an involvement in an election. I walked around vaguely sick to my stomach, feeling beaten down," Comey said in an interview with ABC's George Stephanopoulos.

"I felt like I was totally alone, that everybody hated me," he continued. "And that there wasn't a way out because it really was the right thing to do."

Comey publicly said months before the election that Clinton would not be prosecuted for her handling of classified information. However, he wrote a letter just days before Election Day stating the FBI had uncovered new emails.

Though Comey eventually said no new information was found in the emails, Clinton’s team blamed the letter for her sharp drop in the polls leading up to the election.

Comey’s interview coincided with the release of his book, “A Higher Loyalty: Truth, Lies, and Leadership,” which details his interactions with the president and the fallout from the 2016 presidential campaign.
