WASHINGTON — President Trump may be seeking “retribution” against his political foes in at least one case — and there’s a good reason why, according to White House chief of staff Susie Wiles.

The Justice Department’s so far unsuccessful prosecution of New York Attorney General Letitia James could be payback for James’ civil case against the president, where she won a $500,000 fine.

James has “half a billion dollars of his money!” Wiles said in an interview published Tuesday.

Wiles stressed to Vanity Fair that the 45th and 47th president was not “on a retribution tour” but is possibly eager to see his Department of Justice prosecute James for allegedly lying to secure a loan for a second home — after the New York AG dragged him into court for misrepresenting the value of his real estate empire.

“I don’t think he’s on a retribution tour,” Wiles told journalist Chris Whipple. “A governing principle for him is, ‘I don’t want what happened to me to happen to somebody else.’ And so people that have done bad things need to get out of the government. In some cases, it may look like retribution. And there may be an element of that from time to time. Who would blame him? Not me.”

Whipple asked whether “all of this talk … about accusing Letitia James of mortgage fraud” was part of that.

“Well, that might be the one retribution,” Wiles admitted.

“So you haven’t called him [out] on that, or said, ‘Hey, wait a minute,’” Whipple pressed.

“No, no, not on her,” the White House chief of staff responded. “Not on her. She had a half a billion dollars of his money!”

Wiles laughed when noting the whopping $500 million civil fine James secured in the case against Trump, according to Whipple.
