NEW YORK – Steel barriers separated crowds of protesters, roads were closed and traffic was diverted across a swath of Manhattan on Tuesday as former President Donald Trump arrived at a Manhattan courthouse for his arraignment.

Trump, who pumped his fist defiantly as he exited Trump Tower minutes earlier, was placed under arrest upon his arrival at the courthouse. Wearing a dark suit and red tie, Trump waved to the crowd as helicopters whirred above before he stepped inside.

Later, Trump was seen on camera somberly entering a courtroom to hear the charges against him. He pleaded not guilty to all 34 counts of falsifying New York business records to conceal damaging information and unlawful activity during the campaign before the 2016 presidential election.

Trump is the first former commander in chief to face criminal charges. During a prolonged arraignment, the judged warned him against using rhetoric that could inflame or cause civil unrest.

Trump then left the courthouse without addressing reporters. “He’s frustrated, he’s upset,” Todd Blanche, one of Trump’s lawyers, said at a news conference after the proceedings. 

Earlier, New York Mayor Eric Adams and Police Commissioner Keechant Sewell said they had been preparing for the arraignment for weeks and warned protesters that violence “will never be tolerated in our city.”

Developments:

►On his way to the courthouse, Trump posted on his Truth Social site, saying: “Seems so SURREAL –  WOW, they’re going to ARREST ME. Can’t believe this is happening in America. MAGA!”

‘A very historic day’: Scores line up for seat in courtroom

The line for a seat in the judge’s courtroom or two overflow courtrooms had grown close to 100 – mostly members of the media – before dawn Tuesday. Mike Magliano, one of the court officers on the scene, explained that members of the media could leave after obtaining a pass, then come back at 1 p.m. Passes were distributed at 8 a.m.

“Don’t lose that ticket. It’s the hottest ticket in town,” he said. 

Up the block across from the court, Gregory Williams, 57, who came down from the Bronx, was seated next to a Hillary Clinton cardboard cutout and a sign that said, “Lock him up.”

“Today is going to be a very historic day,” Williams said. In the end, though, Williams said Trump was likely to benefit more than anyone from the media circus around the proceedings.

“In reality today is just a Trump mega-campaign event,” Williams said.

‘Typical processing’ – but no handcuffs

Trump lawyer Joe Tacopina said Tuesday that Trump will undergo normal arraignment processing, which generally includes fingerprints, mugshots and paperwork.

“I think there will be a typical processing, which does not take long, 20-30 minutes. There won’t be handcuffs,” Tacopina told ABC’s Tight security at courthouse, Trump Tower

The city has stationed officers and put up steel barriers near the courthouse and Trump Tower, where Trump stayed Monday night. The heavy police presence is designed to  prevent a repeat of the Jan. 6, 2021, riot in Washington, after Trump urged thousands of supporters to stop President-elect Joe Biden from taking office.

Adams acknowledged that there may be “rabble rousers” taking to the streets, but added that “our message is clear and simple. Control yourselves. New York City is our home, not a playground for your misplaced anger.”
