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.

Donald Trump's former personal attorney and fixer Michael Cohen said the ex-president is likely "seething" over the indictment because he's "never been held accountable."

"The fact that he is being held accountable, something that he has no desire to ever be. He's never been held accountable," Cohen told ABC News' George Stephanopoulos in an interview Friday on "Good Morning America."

"This is a man who held up the Bible and said he's never apologized to God because he's never done anything wrong," he added. "He doesn't understand accountability. And right now, [Manhattan District Attorney] Alvin Bragg has finally put that into his lap."

Cohen, who is now estranged from Trump and is a key prosecution witness, said he decided years ago that his "loyalty can no longer be to a man who doesn't deserve it."

Cohen was sentenced to three years in prison in December 2018, after pleading guilty to violating federal campaign finance law in connection with hush-money payments and lying to Congress, among other crimes.

During Friday's interview on "GMA," Cohen said he followed Trump's "message" for more than a decade and "that is what got me in trouble."

When asked if he feels ready to be cross-examined, Cohen replied: "Absolutely."

"The documents will speak for themselves," he added, referring to the sealed indictment.

"So, not just your testimony?" Stephanopoulos responded.

"No," Cohen said. "And it's also corroborating testimony, but it's documents."
