In a post on his social media platform Truth Social, Trump said he would surrender to authorities in Georgia. The former president faces four criminal cases, including one accusing him of illegally scheming to overturn his 2020 election loss to Joe Biden.

In the Georgia case, in which he and 18 co-defendants were indicted last week, prosecutors allege that the former president, his top campaign staff members, and other supporters helped to solicit fake voters and falsely swear they would cast votes for Trump to win the state in a bid to reverse his defeat. The case against him and the other defendants alleges a pattern of racketeering, among other charges.

The court filing said that when Trump reports to the Fulton County jail, authorities will take a mug shot and process paperwork. Defendants typically also have their height and weight recorded at the time of their booking, but Trump asked his lawyers and the US Secret Service to get him an exemption from that part of the process.

A judge will decide whether to grant that request. In the meantime, he has already ordered that Trump pay a $200,000 bond and not send threatening social media messages as he awaits trial. Those orders included in the bail agreement with prosecutors on Monday will continue to apply until he is freed from custody.

Sources familiar with the case tell CNN that Trump and the other co-defendants are expected to surrender on Thursday morning. They have been told they can expect to spend about a month in the county jail. The bond agreement also bars Trump from discussing the case details with his co-defendants or witnesses unless done through their attorneys.

If convicted in the case, which is expected to be called to trial in March, he could face up to a year in prison. Trump has pleaded not guilty to all charges against him and has attacked those involved in the case. He has slammed the district attorney, Fani Willis, for what he says is her witch hunt.

The other cases against him include:

A conspiracy charge in Washington.

An election interference charge in Florida.

A fraud charge in New York involving his hush money payment to porn star Stormy Daniels.

Attorney John Eastman, who represents Trump in the election case in Georgia, is due to appear in a discipline hearing in California on Tuesday and Wednesday. Sources say he will miss the hearings because of his planned surrender in Georgia. The State Bar of California could strip him of his license to practice law if it finds that he violated ethics rules related to the case. Those rules require attorneys to avoid impeding the administration of justice by taking “impeccable, inexcusable or indefensible” actions that involve dishonesty. The attorney is also fighting the charges in a separate civil lawsuit filed by the Federal Trade Commission. The FTC alleges that Eastman and other Trump campaign officials misled donors to the campaign by failing to disclose a payment from an undisclosed souce.
