Lying Long Island Rep. George Santos said he will not resign — and blasted the fraud and money laundering charges against him as a “witch hunt” — after he was released from federal custody on $500,000 bond Wednesday.

Santos, 34, was mobbed by reporters and cameras as he left federal court in Central Islip — telling the crowd that he still planned to run for reelection and would be heading back to Washington.

“Now I’m going to have to go fight to defend myself,” Santos said. “The reality is that it’s a witch hunt.”

Earlier, a put-together Santos appeared in court wearing a blue blazer, white shirt, black sweater and khakis and calmly entered a “not guilty” plea to a 13-count indictment as a packed courtroom looked on.

Santos is accused of embezzling $50,000 in campaign money for designer duds and personal expenses, cheating his way to COVID unemployment pay and lying to Congress about his income.

The openly gay GOP lawmaker — who reps the 3rd District on Long Island and Queens — is charged with seven counts of wire fraud, three counts of money laundering, one count of theft of public funds, and two counts of making false statements to the House of Representatives.

He faces up to 20 years in prison if convicted of the top charges.

Judge Anne Shields agreed to release Santos on bail on the conditions that he turn over his passport and limit his travel to within the Tri-state area and Washington DC — unless he is otherwise given permission.

According to the indictment, Santos solicited two separate $25,000 payments from two donors in October 2022 under the pretense that the money would go toward funding his campaign. But instead, Santos spent the money to pay his bills, credit cards and debt and also spent it on “personal purchases of luxury designer clothing,” the court papers allege.

He also allegedly lied on statements to the House of Representatives in 2020 and in 2022 — either inflating certain assets and income while failing to disclose others, the indictment charges

And he claimed to be unemployed from June 2020 through April 2021 despite earning $120,000 at a job during the same time period.

Santos made national headlines last year after admitted to an elaborate series of lies about his education, work background and family history. New York Republican law makers have called for him to step down.
