Hillary Clinton wishes you a happy James Comey Letter Day, which will be henceforth celebrated/mourned every October 28 to mark what Clinton insists is what cost her the 2016 election.

In her book What Happened and in numerous media appearances since her surprise election loss to President Donald Trump, Clinton has pointed to the October 28 letter Comey sent to Congress as determinative in her defeat.

"I was on the way to winning" the race until the then-FBI Director sent the letter that day, Clinton said in May. Clinton has repeatedly blasted Comey for the move, saying there was no justification for it and that the news coverage of the letter destroyed her momentum against Trump.

Comey informed lawmakers in the letter that investigators had found Clinton emails on the computer of former Congressman Anthony Weiner, the estranged husband of her top aide Huma Abedin.

Weiner was being investigated over his sexting with an underage girl, a case to which he pleaded guilty earlier this year and was sentenced to nearly two years in prison.

Despite the letter, pundits continued to confidently predict Clinton would be victorious, and Clinton herself said she fully expected on Election Day to win.

Comey later said it made him "mildly nauseous" to think his letter affected the race but stipulated he would have made the same decision again.
