NEW YORK, March 31 (Reuters) - Donald Trump is due to be fingerprinted and photographed in a New York courthouse next week as he becomes the first former U.S. president to face criminal charges in a case involving a 2016 hush money payment to porn star Stormy Daniels.

Trump's expected appearance before a judge in Manhattan on Tuesday, as the Republican mounts a bid to regain the presidency, could further inflame divisions in the United States. A New York judge in a document unsealed on Friday authorized Manhattan District Attorney Alvin Bragg, a Democrat, to disclose that Trump had been indicted, but it was not clear when the specific charges would be made public.

Trump plans to fly to New York on Monday from his Mar-a-Lago estate in Florida and spend the night at Trump Tower before appearing in court early on Tuesday, according to a person familiar with the matter. Trump plans to return to Florida afterward, the source said.

Susan Necheles, a Trump attorney, told Reuters he will plead not guilty. Necheles said she did not expect the charges to be unsealed until Tuesday.

"I am not afraid of what's to come," Trump said in a fundraising email on Friday.

For nearly two weeks, Trump has been using the various legal troubles he faces to rally supporters and raise money as he seeks his party's nomination to challenge Democratic President Joe Biden next year in a rematch of the 2020 election. His campaign said Trump raised more than $4 million in the 24 hours following the news of his indictment by a Manhattan grand jury.

The first American president to try to overthrow an election defeat, inspiring the deadly 2021 assault on the U.S. Capitol, has signaled he will continue to run despite the charges.

Biden on Friday kept his thoughts on the charges against his political rival to himself, telling reporters: "I'm not going to talk about Trump's indictment."

After word surfaced on Thursday about the indictment, Trump called himself "completely innocent" and a victim of political persecution.

On Friday, Trump lashed out at Justice Juan Merchan, the judge expected to oversee the case. Trump wrote on social media that Merchan, who also presided over last year's trial in which his real estate company was convicted of tax fraud, "HATES ME" and treated the Trump Organization "VICIOUSLY." Trump was not charged in that case, which also was handled by Bragg's office.
