ABC News has learned that former president Donald Trump has been indicted, according to multiple sources with knowledge. The charges were not immediately clear.

Manhattan District Attorney Alvin Bragg has notified Trump.

Trump's former attorney, Michael Cohen, said in a statement, "I do take solace in validating the adage that no one is above the law; not even a former President."

"Today’s indictment is not the end of this chapter; but rather, just the beginning," Cohen said. "Accountability matters and I stand by my testimony and the evidence I have provided to [the district attorney's office]."

The Manhattan grand jury weighing charges against former President Donald Trump will not convene on Wednesday and is expected to meet Thursday on other matters, sources familiar with the situation told ABC News.

The proceeding is conducted in secret and the grand jury could be presented with evidence or vote at any time.

David Pecker, the former publisher of the National Enquirer, was seen leaving the Manhattan District Attorney’s Office with his lawyer on Monday.

Pecker testified before the grand jury for about an hour, sources familiar with the matter told ABC News.

Pecker, who allegedly helped arrange the payment to Stormy Daniels before the 2016 election, previously spoke to the grand jury in January.

The district attorney’s office may have called Pecker to bolster Michael Cohen’s earlier testimony about the purpose of the payment.

The Manhattan grand jury weighing charges against former President Donald Trump is expected to reconvene on Monday, sources tell ABC News.

The grand jury may hear from another witness on Monday.

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.
