Trump indictment: New York grand jury votes to indict Donald Trump;  delivery is expected early next week

NEW YORK — A Manhattan grand jury has indicted former President Donald Trump, making him the first president or former president to face criminal charges.

It was not immediately clear what the charges were related to, or what charges Trump would face. The charge was under seal.

Manhattan District Attorney Alvin Bragg's office said in a statement that they had contacted President Donald Trump's former attorney “to coordinate his submission” to the indictment of the state Supreme Court indictment, noting it remained undisclosed.

“Guidance will be provided when an indictment date is selected,” the office said.

The former president is expected to turn himself in in New York early next week, a source familiar with the matter told ABC News. While no day has been set yet, sources say that Tuesday is the day Trump's legal team and the DA's office are discussing.

Trump told ABC News by phone that the charges were “an attack on our country.”

He called it “political persecution”, adding, “they are trying to influence elections.”

Trump's attorneys said in a statement Thursday, “He has not committed any crimes. We will vigorously fight these political charges in Court.”

All NYPD officers have been ordered to appear in uniform on Friday to be posted around the city, a police source told ABC News.

There was no credible threat, according to the mayor's office.

DC Police told ABC News they were not aware of any upcoming First Amendment activity following President Donald Trump's indictment.

“MPD will continue to monitor and will develop appropriate plans with our federal law enforcement partners to ensure the safety of DC residents and visitors,” Police told ABC News in a statement.

The White House declined to comment on the charges.

Trump's former attorney, Michael Cohen, said in a statement, “I take comfort in validating the adage that no one is above the law; not even former Presidents.”

“Today's indictment is not the end of this chapter; it is only the beginning,” Cohen said. “Accountability matters and I stand by my testimony and the evidence I provided (prosecutor's office).”

The grand jury has heard from witnesses including Cohen, who said he arranged payments in 2016 to two women to silence them about sexual relations they said they had with Trump a decade earlier.

Daniels' attorney, Clark Brewster, issued a statement on the charges, saying: “The indictment of Donald Trump is no cause for joy. The hard work and conscience of the grand jury must be respected. Now let truth and justice prevail. No one is above the law.”

Trump denied the meeting took place and said he did nothing wrong, calling the investigation a “witch hunt” by a Democratic prosecutor bent on sabotaging the Republican Party's 2024 presidential campaign.

Bragg's office has been examining whether any state laws were violated in connection with the payments or the way Trump's company compensated Cohen for his work to keep the women's allegations secret.

Daniels and at least two former Trump aides — former political adviser Kellyanne Conway and former spokeswoman Hope Hicks — are among witnesses who have met with prosecutors in recent weeks.

Cohen said that at Trump's direction, he arranged a $280,000 payment to Daniels and Playboy model Karen McDougal. According to Cohen, the payment was to buy their silence about Trump, who was then in the midst of his first presidential campaign.

Cohen and federal prosecutors said the company paid him $420,000 to recoup a $130,000 payment to Daniels and to cover bonuses and other dues. The company classifies the payment internally as legal fees.

The $150,000 payment to McDougal was made by the publisher of the supermarket tabloid National Enquirer, which kept the story from unfolding.

Federal prosecutors agreed not to sue the Enquirer parent company in exchange for its cooperation in the campaign finance investigation that led to the indictment against Cohen in 2018. Prosecutors said the payments to Daniels and McDougal constituted an impermissible and unrecorded gift to Trump's election bid.

Cohen pleaded guilty, served time in prison and was fired. Federal prosecutors have never charged Trump with any crime.

The Democratic National Committee said in a statement Thursday, “No matter what happens in Trump's impending legal proceedings, it is clear the Republican Party stands by Donald Trump and the MAGA Republican Party.”

The DNC vowed, “We will continue to hold Trump and all Republican candidates accountable for MAGA's extreme agenda that includes banning abortion, cutting Social Security and Medicare, and undermining free and fair elections.”

Republican National Committee Chair Ronna McDaniel called the indictment “a blatant abuse of power by an DA focused on political revenge.”

“When our justice system is weaponized as a political tool it puts us all in danger,” he tweeted.

House Speaker Kevin McCarthy said in a tweet that the House GOP would use its powers to hold Manhattan District Attorney Alvin Bragg accountable “and for his unprecedented abuse of power.”

“The American people will not tolerate this injustice,” McCarthy said, adding that Bragg had “weaponized our system of sacred 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 said he would not comply.
