In his first post on social media since his arraignment, former President Donald Trump called the hearing "shocking" that there were "no surprises" and "no case."

Trump also promoted his upcoming speech tonight at Mar-a-Lago on his social media platform.

"Just lifted off for Palm Beach, Florida. Will be delivering remarks tonight at Mar-a-Lago at 8:15 P.M., EASTERN. The hearing was shocking to many in that they had no 'surprises,' and therefore, no case. Virtually every legal pundit has said that there is no case here. There was nothing done illegally!" Trump wrote.

ABC News asked legal experts their thoughts on the indictment and statement of facts document unsealed Tuesday in the Manhattan district attorney's case against former President Donald Trump.

According to Lance Fletcher, a former assistant district attorney at the Manhattan DA's Office, the indictment "discusses an intent to defraud, and an intent to commit another crime, but does not specify what that other crime is."

"This is an important issue because the intent to defraud and intent to commit another crime is what bumps this up from a misdemeanor to a felony," Fletcher continued.

The timing of meetings and payments relative to the 2016 election is also important "because it indirectly argues purpose was campaign-related and not for Trump's personal reasons (such as keeping his marriage together)," Fletcher said.

Marc Scholl, who was a prosecutor in the Manhattan District Attorney's Office for nearly 40 years and is now in private practice with the New York-based firm Lewis Baach Kaufmann Middlemiss, called the statement of facts document "an oddity."

"Why it was not part of the indictment as a conspiracy count is odd, but I guess the DA didn't want to have a misdemeanor," Scholl said, adding that statements of facts like this "are not commonplace."

Scholl noted that the district attorney doesn't need to prove anything that's said in the statement of facts -- just what’s in the indictment.

Michael Bachner, a former assistant district attorney in the Rackets Bureau of the Manhattan DA's Office, said the only surprise in the indictment was "it being expanded to include [former Playboy model Karen] McDougal."

"The theory of the prosecution is exactly as we expected and that is that there was a scheme to bury stories through this catch-and-kill process in order to help Donald Trump get elected, and that these payments were in the campaign contributions which were improperly buried," Bachner continued.

As far as next steps, Trump's attorneys are now "obviously going to file some very significant motions to dismiss the indictment," including by citing statute of limitations, and the theory "that there was no effort to interfere with an election," Bachner said.

"This was all payments made for personal purposes. However, given the timing of the payment is right after the Access Hollywood story, I think the judge is going to let this indictment stand," Bachner said.

With former President Donald Trump being arraigned on 34 felony counts of falsifying business records related to Stormy Daniels -- to which he pleaded not guilty -- comes the reminder of when Trump first broke his silence about the adult film star.

It was on April 5, 2018, when Trump walked back to where reporters were seated on Air Force One and denied, when questioned, that he knew about a reported $130,000 hush money payment made by his then-lawyer Michael Cohen to Daniels.

In Trump's attorneys' first public comments following Tuesday's arraignment, Todd Blanche said "there were no surprises" in the indictment and that they "plan to fight it hard."

Trump is "upset and frustrated and disappointed and mad that this happened," Blanche told reporters outside the Manhattan courthouse.

Joe Tacopina, another Trump attorney, called the case insufficient and said the unsealing of the indictment "shows that the rule of law died in this country."

"While everyone is not above the law, no one's below it either," Tacopina said. "And if this man's name was not Donald J. Trump, there is no scenario we'd all be here today."
