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.

Former President Donald Trump can still be elected president -- even if he is convicted -- experts tell ABC News. But there are practical reasons that could make it a challenge, experts say.

Trump said recently at the annual Conservative Political Action Conference that he would "absolutely" stay in the race for president even if he were to be criminally indicted.

Trump has denied wrongdoing and has characterized the probe as part of a "witch hunt" against him.

The U.S. Constitution does not list the absence of a criminal record as a qualification for the presidency.

Constitutional experts also told ABC News that previous Supreme Court rulings hold that Congress cannot add qualifications to the office of the president. In addition, a state cannot prohibit indicted or convicted felons from running for federal office.
