According to law, former President can be elected president if indicted -- or even convicted -- in any of the state and federal investigations he is currently facing, experts tell ABC News. But there are practical reasons that could make it a challenge, experts say.

Trump said earlier this month at the annual Conservative Political Action Conference that he would "absolutely" for president even if he were to be criminally indicted.

"I wouldn't even think about leaving," Trump told reporters ahead of a speech. "Probably it will enhance my numbers."

The Manhattan grand jury weighing charges against former President Donald Trump in connection to the Stormy Daniels hush payment investigation is not meeting on Wednesday, sources told ABC News. The earliest the grand jury would reconvene is Thursday, sources said.

The grand jurors were called Wednesday morning and told they were not needed during the day as scheduled, sources familiar with the matter told ABC News. The grand jurors were told to be prepared to reconvene on Thursday when it’s possible they will hear from at least one additional witness, the sources said.

The Manhattan district attorney’s office declined to comment, citing a policy of not discussing grand jury matters.

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.

Former Vice President Mike Pence discouraged any protests should a grand jury indict Donald Trump.

"Every American has the right to let their voice be heard. The Constitution provides the right to peaceably assemble. But I think in this instance, I would discourage Americans from engaging in protests if in fact the former president is indicted," Pence said Tuesday when asked by ABC News if Americans should protest a possible indictment.

Pence said he understood the "frustration" while calling the case "politically motivated."

"But I think letting our voices be heard in other ways, and in not engaging in protests, I think is most prudent at this time," he said.

As legal experts speculate on what charges lay inside the sealed indictment ahead of former President Donald Trump's expected surrender on Tuesday afternoon, many predict that prosecutors could try out a new legal theory to justify bringing the charges.

"This could be a novel legal theory," said Kate Shaw, a law professor at Cardozo and ABC News contributor, speculating on what charges the public could see against Trump while stressing it's unknown until the indictment is unsealed.
