Publicist Trevian Kutti has surrendered to authorities at the Fulton County Jail, leaving only one defendant remaining to turn themselves in before the DA's noon deadline, according to the Fulton County Sheriff's Office.

Former Justice Department official Jeffrey Clark, Georgia state Sen. Shawn Still, former Coffee County elections director Misty Hampton, Georgia lawyer Robert Cheeley and Trump staffer Michael Roman all surrendered for processing since last night, the sheriff's office said.

The last remaining defendant is Chicago pastor Stephen Lee, who officials said is expected to surrender today.

Defendant John Eastman, who faces nine counts in the DA's indictment, said Trump's surrender to authorities Thursday was "a crossing of the Rubicon in our system of justice."

Speaking last night outside the California Bar Court where he is fighting disbarment, the former Trump attorney said he will mount a strong defense to the DA's case.

"We have very viable legal defenses and constitutional defenses," said Eastman, who was processed and released from Fulton County Jail Wednesday.

Eastman, who is accused of drafting a plan for Trump to cling to power by falsely claiming then-Vice President Mike Pence could reject legitimate electors during the Jan. 6 certification of the vote, has indicated that he will seek to sever his case from the other defendants.

"It's because we'd like to get out of it sooner," he told ABC News. "Because we did nothing wrong."

Following Donald Trump's surrender for processing on Thursday night, five more defendants in the case surrendered overnight at the Fulton County Jail.

Out of the 19 total defendants, only Trevian Kutti and Stephen Lee have yet to turn themselves in as today's noon deadline approaches.

Both Kutti, a publicist who once repped Ye and R. Kelly, and Lee, an Illinois pastor, are accused of trying to strong-arm election worker Ruby Freeman, who was falsely accused of stealing ballots.

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.
