Trump has posted his mug shot on his X account, marking his first post on the social media platform since Jan. 8, 2021.

Trump was suspended from X -- then known as Twitter -- following the attack on the U.S. Capitol on Jan. 6, 2021. He hadn't tweeted since new owner Elon Musk reinstated his Twitter account in November 2022 -- instead using his Truth Social platform to post messages.

Trump posted his mug shot on Truth Social as well.

Both posts linked to Trump's 2024 campaign website, where the mug shot was also used as part of a fundraising pitch.

The Fulton County Sheriff's Office has released the mug shot taken of Trump during his processing this evening.

This is the first mug shot to be taken of Trump among his four indictments.

In remarks before boarding his plane at Hartsfield-Jackson Atlanta International Airport, Trump said he had the right to challenge an election "we think is dishonest."

"We did nothing wrong," said Trump, continuing to falsely claim that the election had been stolen.

"We have every right to challenge the election," he said.

Trump's plane is now en route to Newark Liberty International Airport.

Trump's motorcade is now en route to Hartsfield-Jackson Atlanta International Airport following his booking and release from the Fulton County Jail.

Attorney John Eastman was booked and released on $100,000 bond Tuesday at the Fulton County Jail, as the 18 defendants charged alongside former President Trump in the sweeping Georgia election interference racketeering case began turning themselves in.

Eastman told reporters on his way out of the facility that he plans to "vigorously contest every count of the indictment."

Co-defendant Scott Hall was also processed and released Tuesday, one day after Judge McAfee set his bail at $10,000. Hall, a Georgia bail bondsman, is among those accused of conspiring to commit election fraud in Coffee County.

After an indictment has been handed down in Georgia, bond and conditions of release are typically worked out prior to any surrender. The bond can be paid through cash, a commercial surety, or a court program that requires a payment of 10% of the bond amount.

By the end of the day Tuesday, bond had been set for more than half of the 19 defendants in the case. Fulton County Superior Court Judge Scott McAfee set former Trump attorney Jenna Ellis' bail at $100,000, a day after he set former President Donald Trump's bond at $200,000.

Ellis is accused of making false statements to overturn the 2020 election and of soliciting public officials to unlawfully appoint presidential electors.

Later Tuesday the judge set bond for Stephen Lee, a pastor, at $75,000, and for Georgia lawyer Robert Cheeley at $50,000.

According to investigators, Cheeley presented video clips to legislators of election workers at the State Farm Arena in Atlanta and alleged that the workers were counting votes twice or sometimes three times. Prosecutors say Lee worked with others to try to pressure Georgia election worker Ruby Freeman and her daughter after Trump and his allies falsely accused them of pulling fraudulent ballots from a suitcase during the vote count.

McAfee also Tuesday set bail of $75,000 for former Coffee County GOP chair Cathy Latham, and $50,000 for former Trump campaign official Michael Roman.

Latham is one of 16 Georgia Republicans who signed a certificate falsely stating that Trump had won the state, while Roman served as director of Election Day operations for Trump's 2020 reelection campaign and was involved in the plan to organize the so-called "fake electors" in battleground states.

All 19 defendants have been been given until Friday at noon to surrender. Trump said Monday evening on his social media platform that he intends to surrender in Georgia on Thursday.

In addition to Trump, Judge McAfee set bond Monday for attorneys John Eastman and Kenneth Chesebro at $100,000, for Ray Smith III at $50,000, and for Scott Hall at $10,000.

All the defendants' bond agreements include a provision that they "shall perform no act to intimidate any person known to him or her to be a codefendant or witness in this case or to otherwise obstruct the administration of justice."
