Former President Trump is expected to surrender in New York early next week, sources familiar with the matter told ABC News.

While a day has not been firmed up, sources said that Tuesday is the day being discussed by Trump's legal team and the Manhattan District Attorney's Office.

House Speaker Kevin McCarthy said in a tweet that the House GOP will use its power to hold Manhattan District Attorney Alvin Bragg "and his unprecedented abuse of power to account."

"The American people will not tolerate this injustice," McCarthy said, adding that Bragg has "weaponized our sacred system of justice against President Donald Trump."

House Republicans have requested documents and testimony from the Manhattan District Attorney's Office in its investigation of Trump, but Bragg has said he won't comply.

Manhattan District Attorney Alvin Bragg's office said in a statement that it has contacted former President Donald Trump's attorney "to coordinate his surrender" for arraignment on a state Supreme Court indictment, noting that it remains under seal.

"Guidance will be provided when the arraignment date is selected," the office said.

In the wake of the indictment, all officers with the New York Police Department have been ordered to show up in uniform Friday morning for deployments around New York City, police sources told ABC News.

There are no credible threats, according to the mayor's office.

Criminal prosecution proceedings typically start with an arrest and a court appearance, but legal experts say that on many occasions, especially in white collar crimes, suspects aren't hit with charges or a visit from an officer until long after an official investigation is underway.

Typically, if a crime is being investigated, law enforcement agents will make an arrest, file initial charges and bring a suspect to be arraigned in court, Vincent Southerland, an assistant professor of clinical law and the director of the criminal defense and reentry clinic at NYU School of Law, told ABC News.

After this arraignment, prosecutors would impanel a grand jury for a formal criminal indictment. Southerland, who has been practicing law in New York state for 19 years, said this process includes giving the jury evidence, possible testimony and other exhibits before they can officially charge a person with felonies.

A Manhattan grand jury is currently investigating Trump's possible role in the hush payment to adult film actress Stormy Daniels. The former president has denied any wrongdoing and having an affair with Daniels. His attorneys have framed the funds as a response to an extortion plot.
