There will be no other court proceedings on the 15th floor of the New York State Supreme Courthouse while Donald Trump is there for his arraignment, according to a court official.

A number of other state Supreme Court cases have been adjourned to limit the number of people in the courthouse during the former president’s appearance.

The streets around the building will be blocked off and traffic stopped during Trump's movements to and from the building.

Court security officers and the U.S. Secret Service will handle security inside and the immediate perimeter. The NYPD will contribute and also work a wider perimeter, handle traffic and monitor any protests.

While 45% of Americans believe former President Donald Trump should face charges in an investigation by the Manhattan District Attorney's Office, 32% say he shouldn't have been indicted, according to a new ABC News/Ipsos poll.

Another 23% of American say they don't know whether the nation's 45th president should face charges.

While the charges have not been announced, a Manhattan grand jury that indicted Trump had been hearing evidence in a $130,000 hush money payment Trump allegedly made to adult film actress Stormy Daniels, who claims they had an affair. Trump has denied the allegations.

The poll showed a split in opinions along party lines. While 88% of Democrats said Trump should face charges, 62%, of Republicans said the former president should not have been charged while 16% said he should be charged, and the remainder was uncertain.

About 47% of Americans polled say the charges are politically motivated, echoing the sentiment from top GOP figures. About 79% of Republicans hold that view.

Trump's lawyer said on Sunday on ABC's "This Week" that he doesn't know what to expect when the former president is arraigned on Tuesday in New York City, given the historic nature of Trump's indictment.

"This is unprecedented. I don't know. I've done a million arraignments in that courthouse with celebrities and whatnot. But this is a whole different thing. We have Secret Service involved. I understand they're closing the courthouse for the afternoon. I just don't know what to expect to see," Joe Tacopina told "This Week" anchor George Stephanopoulos.

He likened the case to "persecution" and said the charges, which remain under seal, "revolved around" Trump paying money to adult film actress Stormy Daniels before the 2016 election to keep her from going public with a claim of an affair that Trump denies.

He told Stephanopoulos that he didn't know whether Trump would hold a press conference on Tuesday after he is arraigned.

"What I hope is that we get in and out of there as quickly as possible, that it's, at the end of the day, a typical arraignment," he said.

Donald Trump's attorney, Joe Tacopina, said the former president's initial reaction to his indictment was "shock," despite predicting his own arrest "based on rumours and leaks."

"It was shock because it's actually coming to fruition," Tacopina told ABC News' George Stephanopoulos in an interview Friday on “Good Morning America.”

"At the end of the day, we were really hoping and he was hoping that the rule of law would've prevailed," he added. "In my opinion -- and I don't say this with pride or pleasure -- in my 32 years as a lawyer, both as a prosecutor and a defense attorney, I feel like the rule of law died yesterday in this country."

When asked what to expect next week, Tacopina said "it's a great question."

"This is unprecedented in this country's history. I don't know what to expect other than an arraignment," he said. "I understand they're going to be closing off blocks around the courthouse, shutting down the courthouse. You know, we'll go in there and we'll proceed to see a judge at some point, plead not guilty, start talking about filing motions, which we will do immediately and very aggressively regarding the legal viability of this case."

Tacopina noted that "there is really no precedent for this case, [because] this was done with personal money."

"Statutorily, the law says this: If the payment was made with personal funds and it would've been made irrespective of the candidate's campaign, it's outside of campaign finance and, clearly, that's what you have here,” he said.

When asked whether there will be handcuffs, a mugshot or a perp walk, Tacopina responded: "I'm sure they will try to get every ounce of publicity they can out of this thing."

"The president will not be put in handcuffs," he added. "As far as a mugshot's concerned, perp walk, I mean, you know, as I said, I'm sure they'll try to make sure they get some joy out of this by parading him."

"But, you know, I think this is a different situation," he continued. "It is a lot of groups involved here and I don't think they're going to allow this to become a circus, as much as humanly possible."

When asked how concerned he is about this case and the other potential cases Trump could be facing, Tacopina said: "We have to deal with it one at a time."

"Right now, I'm dealing with this case exclusively and another civil matter for the president, but not the Fulton County case and not the special prosecutor's case at this point," he added. "And really, I'm not even thinking about those cases at all. I'm focused -- laser focused -- on this case and I'll keep all my attention here until this is resolved."
