After months of rallies that included "lock her up!" chants and a threat to put her in jail, President-elect Donald Trump now says he won't pursue charges against Hillary Clinton and supporters are revolting over it.

The announcement came this morning from Trump aide Kellyanne Conway who, appearing on MSNBC's Morning Joe, confirmed Trump wouldn't pursue charges against Clinton for the email server scandal.

"I think Hillary Clinton still has to face the fact that a majority of Americans don't find her to be honest or trustworthy. But if Donald Trump can help her heal, then perhaps that's a good thing," Conway said.

The kicker, though, was when Conway said, "I think he's thinking of many different things as he prepares to become president of the United States and things that sound like the campaign aren't among them."

(It should be noted that the authority to pursue such charges actually rests with the Department of Justice, not the president, but Trump has never been one to let facts get in the way of rhetoric.)

As the news spread, Trump supporters took to Twitter to calmly share their displeasure, voicing polite disagreement with Trump's decision to back away from one of his biggest campaign promises just two weeks after the election.

The bitch is going to walk again. So much for lock her up. — Denyse Lake (@DenyseLake) November 22, 2016

Even Breitbart, the alt-right, pro-Trump website that gave the president-elect favorable coverage and his new lead advisor, Steve Bannon, wasn't happy with the decision.

The emotional backlash isn't really a surprise. A recent poll by YouGov and The Economist showed that 62 percent of Trump voters believed in his campaign promise to appoint a special prosecutor to open a new investigation into Clinton's use of a private email server (which she has already been cleared of — twice).

Believed Trump would actually ask a special prosecutor to investigate Clinton:

@realDonaldTrump @KellyannePolls Hillary would, and is still trying to steal the election from Trump right now if she could. LOCK HER UP! — AJROSS (@AJ641G) November 22, 2016

Perhaps it also shouldn't be a surprise that some are already formulating conspiracy theories about the decision to walk back the promise.

If your not going to appoint a special prosecutor for Hillary. What are you hiding @realDonaldTrump #MAGA — Christopher wilson (@Christo78019511) November 22, 2016

@AnnCoulter @washingtonpost Did Killary made a deal with Trump? Like she promises to give back Clinton Foundation $ and no nude pics? — Tom Dupley (@ThomasDupley) November 22, 2016

And one pro-Trump site has suggested that the decision is to fool President Barack Obama to not issue a pardon for Clinton, leaving her vulnerable to future charges in case Trump changes his mind again.

Mashable has reached out to a Trump spokesperson for further comment.
