Former President Donald Trump is making a stop at Versailles, a restaurant in Little Havana at the heart of Miami's Cuban exile community.

He was greeted with cheers and shook hands and snapped photos with excited supporters.

Some patrons sang "Happy birthday" to Trump, who turns 77 on Wednesday.

"I think it's going great. I think it's a rigged deal here. We have a rigged country," Trump said in brief remarks.

"We're a nation in decline, and then they do this stuff," Trump said. "You see the crowds and everything else -- we have a country that is in decline like never before, and we can't let it happen."

Trump's aide and co-defendant, Walt Nauta, attended the restaurant stop with the former president.

Over the last few days, Trump's campaign team discussed whether the former president should publicly greet supporters while in Florida, in an effort to show him as tough and resilient, and in a setting outside of court.

Former President Donald Trump has left the Miami federal courthouse after pleading not guilty to charges including willful retention of national defense information and conspiracy to obstruct justice.

Trump, alone in the motorcade, with only his Secret Service detail in his car, is next heading to a local business in Miami, sources told ABC News.

Later in the day, Trump will fly to his golf club in Bedminster, New Jersey, where he'll address his supporters Tuesday night.

Defense attorney Todd Blanche entered a not guilty plea on behalf of former President Donald Trump.

Trump was frowning at some points and was looking down toward the floor for most of the hearing.

Trump was already in the courtroom by about 2:45 p.m., ahead of the scheduled 3 p.m. start time. Seated at the same table as Trump was his aide and co-defendant, Walt Nauta.

Trump waited in the courtroom for about 10 minutes before the judge arrived.

At first Trump appeared slumped in his chair, but when the judge asked for him to be officially arraigned, the former president sat up a bit and crossed his arms.

At one point during the arraignment, the magistrate judge asked Trump's lawyers Todd Blanche and Chris Kise if they were permanent attorneys, and they indicated they were.

Trump was barred from speaking to any witnesses about the case, except through counsel.

The court did not impose restrictions on Trump’s travel and his passport was not revoked. There will also be no limitations on his ability to possess a firearm.

Nauta did not enter a plea because he does not have local representation. He's set to return to court on June 27.

Trump never looked back at Smith during the hearing. Trump left the room before the special counsel.

Special counsel Jack Smith in courtroom with Trump

Former President Donald Trump has pleaded not guilty to 37 federal charges.

Special counsel Jack Smith is currently in the courtroom for former President Donald Trump's arraignment. It's very unusual for a top prosecutor to attend such an early court appearance in a case.

This marks the first time Trump and Smith are in the same room.

Other prosecutors and Trump's lawyers are also present.
