Former President Donald Trump can still be elected president again -- even if he is convicted -- experts tell ABC News.

But there are practical reasons that could make it a challenge, the experts told ABC News after Trump was indicted by a Manhattan grand jury in March.

Attorney General Merrick Garland tapped Jack Smith in November 2022 as special counsel to oversee the DOJ's investigation into former President Donald Trump's handling of classified materials after leaving office.

Former colleagues have characterized Smith, a longtime federal prosecutor and former head of the Justice Department's public integrity section, as an aggressive prosecutor who would not shy away from taking on difficult prosecutorial judgments, with the background and temperament that make him a strong selection for the high-profile role.

When the former president arrives at Miami federal court on Tuesday, it will mark an extraordinary moment for the country: Trump will be formally placed under arrest by the very government he was once elected to lead.

Once he is arrested, Trump will be booked and processed as a federal defendant and then appear before a judge for an arraignment.

Trump, or one of his attorneys, will enter a not guilty plea, touching off the prosecution of the former president.

The courthouse has spent the last several days preparing for Trump's arrival, but there is no outward sign Thursday night that he is days away from appearing.

Prior to news of the indictment, members of the special counsel's team were seen going into and out of court and the room where a grand jury has been hearing evidence.

Former President Donald Trump posted on his social network Truth Social Thursday evening that his lawyers have been informed he's been indicted.

He called the investigation a "hoax" and said he's an "innocent man."

Trump said he has been summoned to appear at the Miami federal courthouse on Tuesday.

Trump's campaign sent out a fundraising email following news of the indictment.

Former Vice President Mike Pence, Donald Trump's former running mate turned 2024 presidential campaign rival, said on "The Hugh Hewitt Show" Friday that he was unhappy about the indictment, but added that "no one is above the law."

"I'm deeply troubled to see this indictment move forward," Pence said.

"But let me be very clear: No one is above the law," he added.

"We have to protect our nation's secrets. And my only hope is, as we learn about the facts of this indictment next week, that the American people will see in this case that it would meet a high standard necessary to justify the unprecedented federal indictment of a former president of the United States by, by the current president of the United States' Justice Department and by a potential rival," Pence said.

Pence also called for the indictment to be unsealed and for Attorney General Merrick Garland to address the nation.

"I think before the sun sets today, the attorney general of the United States should be standing in front of the American people, should unseal this indictment, should provide the American people with all the facts and information here. And the American people be able to judge for themselves whether this is just the latest incident of weaponization and politicization at the Justice Department or it's something different," he said.

When asked if FBI Director Christopher Wray "needs to go," Pence did not respond directly but said he would "clean house" if elected president.

"Whether it's the Justice Department or whether it's the FBI, I think -- I just think we need a whole new team. I think there's been a, you know, literally a collapse of confidence," Pence said.
