Trump won't push Clinton investigation: aide

President-elect Donald Trump will not push for further investigation of Hillary Clinton related to her private email use and the Clinton Foundation, a close adviser said Tuesday, breaking with a key campaign theme.

Trump triggered consternation -- and widespread condemnation -- when he made an unprecedented campaign threat to jail his Democratic rival should he win the White House.

The Republican made Clinton's email scandal and allegations of pay-to-play at her family foundation a core theme of his campaign, railing against her "crimes" and leading fired-up supporters in chants of "Lock her Up!"

But since his election he has deflected questioning on the subject, saying in an interview he would think about it, but had other priorities as incoming head of state.

"I think when the president-elect... tells you before he's even inaugurated that he doesn't wish to pursue these charges, it sends a very strong message, tone, and content" to fellow Republicans, Trump aide Kellyanne Conway said in an interview on MSNBC's "Morning Joe."

During their second presidential debate in October, Trump told Clinton he would instruct his attorney general to get a special prosecutor to look into her email practices when secretary of state.

Clinton responded: "it's just awfully good that someone with the temperament of Donald Trump is not in charge of the law in our country."

Trump then quipped: "Because you'd be in jail."

Conway told CNN that Clinton "still has to face the fact a majority of Americans don't find her to be honest or trustworthy."

"If Donald Trump can help her heal, perhaps that's a good thing," she added.

"He's thinking of many different things as he prepares to become the president of the United States, and things that sound like the campaign aren't among them."

Clinton has attributed her loss to the bombshell decision by FBI director James Comey to re-open the probe into her use of a private email server, less than two weeks before the vote.

In a call with donors, she claimed that two letters Comey sent to Congress -- re-opening the probe and closing it again after finding no new evidence of wrongdoing -- had tilted crucial states towards her Republican rival.

Comey's second letter, sent three days before the election, stated that the FBI had not changed its July recommendation not to charge Clinton.
