Senate Majority Leader Chuck Schumer and House Democratic Leader Hakeem Jeffries said in a joint statement Friday, "No one is above the law – including Donald Trump."

"This indictment must now play out through the legal process, without any outside political or ideological interference," they said. "We encourage Mr. Trump’s supporters and critics alike to let this case proceed peacefully in court.”

House Speaker Kevin McCarthy told Fox News he believes the indictment is "going to disrupt this nation because it goes to the core of equal justice for all."

"This is a very dark day in America when you think about what they're trying to indict President Trump on," McCarthy said, falsely equating the crimes Trump allegedly committed with President Joe Biden's own handling of classified documents.

McCarthy said House Republicans "are not going to stand for it," saying he’s already talked to House Oversight Chairman James Comer and House Judiciary Chairman Jim Jordan "of things that we can do to ensure equal justice."

Former President Donald Trump and his aide, Walt Nauta, are set to appear in court at 3 p.m. Tuesday at a federal courthouse in Miami, according to a spokesperson for special counsel Jack Smith.

The indictment was returned Thursday and unsealed on Friday, according to his office.

Trump is expected to arrive at and depart from the Miami courthouse Friday via secure private access points that would make it impossible for the public or journalists to see him.

Secret Service spokesman Anthony Guglielmi said, "While operational security precludes us from going into specifics, the Secret Service will not seek any special accommodations outside of what would be required to ensure the former President's continued safety. As with any site visited by a protectee, the Secret Service is in constant coordination with the necessary entities to ensure protective requirements are met. We have the utmost confidence in the professionalism and commitment to security shared by our law enforcement partners in Florida.

"Miami police will also help Tuesday with "personnel, resources, detours, and/or road closures," Miami Police Chief Manuel Morales said in a statement. "We're committed to protecting everyone's first amendment right and will continue to serve our residents, business owners, and visitors while maintaining the safety of our community."

Special counsel Jack Smith said Friday that he invites everyone to read the indictment "in full to understand the scope and the gravity of the crimes charged."

"The men and women of the United States intelligence community and our Armed Forces dedicate their lives to protecting our nation and its people. Our laws that protect national defense information are critical for the safety and security of the United States, and they must be enforced," he said.

"We have one set of laws in this country, and they apply to everyone," Smith said. "Applying those laws, collecting facts, that's what determines the outcome of an investigation."

The indictment alleged that, after the FBI subpoenaed former President Donald Trump, he "endeavored to obstruct the FBI and grand jury investigations and conceal his continued retention of classified documents by" actions including: suggesting his attorney falsely tell the FBI and grand jury that he didn’t have documents responsive to the subpoena; directing aide Walt Nauta to move boxes of documents to conceal them from Trump’s attorney, the FBI and grand jury; and causing a false certification to be submitted to the FBI and grand jury saying all documents were provided "while knowing that, in fact, not all such documents has been produced."

The indictment noted that between January 2021 and August 2022, Mar-a-Lago hosted more than 150 social events, including weddings and fundraisers "that together drew tens of thousands of guests."

The indictment mentions five of Trump’s statements in 2016, when still a candidate for president, including when he said in August 2016 that "in my administration I’m going to enforce all laws concerning the protection of classified information."

According to the indictment, on June 2, an attorney for Trump went through the boxes in the storage room, removed 38 documents with classified markings, placed them in a redwood folder and sealed it with clear duct tape.

Trump allegedly asked, "Did you find anything?…. Is it bad? Good?" and they discussed what to do with the documents, according to prosecutors.

Trump's attorney said at that point Trump "made a funny motion as though- well okay why don't you take them with you to your hotel room and if there’s anything really bad in there, like, you know, pluck it out. And that was the motion that he made. He didn't say that."

According to the indictment, Trump and Nauta misled one of the Trump attorneys by moving boxes that contained documents with classified markings so that the attorney would not find the documents and produce them to a federal grand jury.

The indictment details how Nauta allegedly lied to FBI agents in May 2022 when he claimed to have no knowledge of the classified documents being brought to Mar-a-Lago.
