Senate Majority Leader Chuck Schumer urged "Trump’s critics and supporters to let the process proceed peacefully and according to the law" in a statement following the indictment of the former president.

"Mr. Trump is subject to the same laws as every American," Schumer said. "He will be able to avail himself of the legal system and a jury, not politics, to determine his fate according to the facts and the law."

Lawmakers on both sides of the aisle took to Twitter to react to the historic indictment on Thursday evening, laying bare the sharp partisan divide when it comes to Donald Trump.

GOP House and Senate members decried the investigation by the Manhattan district attorney as a political prosecution.

Many Democrats, on the other hand, praised the decision as proof "no one is above the law."

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.

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.
