Former President Donald Trump has surrendered at court in lower Manhattan for arraignment on criminal charges.

He traveled in a black SUV with his Secret Service detail. His two lawyers, Todd Blanche and Susan Necheles, were in another SUV.

The motorcade passed a man holding a sign reading, "No one is above the law."

Although the document remains sealed, sources familiar told ABC News that Trump has been charged with around two dozen counts, including felonies.

Still cameras will be permitted inside the courtroom to take photos before the hearing begins, but Judge Juan Merchan has barred video cameras from the proceedings.

Manhattan District Attorney Alvin Bragg is expected to address the media after Trump's arraignment.

Former President Donald Trump has left Trump Tower and is now in a motorcade to a lower Manhattan courthouse to be arraigned.

The indictment against former President Donald Trump has been unsealed.

Prosecutors allege Trump "employed a 'catch and kill' scheme to identify, purchase, and bury negative information about him and boost his electoral prospects," and "went to great lengths to hide this conduct, causing dozens of false entries in business records to conceal criminal activity, including attempts to violate state and federal election laws."

Prosecutors allege, "In one instance, American Media Inc. ('AMI'), paid $30,000 to a former Trump Tower doorman, who claimed to have a story about a child TRUMP had out of wedlock," though the story wasn't true.

"The People of the State of New York allege that Donald J. Trump repeatedly and fraudulently falsified New York business records to conceal crimes that hid damaging information from the voting public during the 2016 presidential election," Manhattan District Attorney Alvin Bragg said in a statement. "The trail of money and lies exposes a pattern that, the People allege, violates one of New York’s basic and fundamental business laws."
