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.

Trump has been booked and released from the Fulton County Jail, according to Fulton County Sheriff’s Office records.

His bond was set at $200,000.

A senior adviser to the former president tells ABC News that a mug shot was taken of Trump moments after he entered the Fulton County Jail.

Trump's height and weight -- listed as 6-foot-3 and 215 lbs. -- were pre-reported in order to speed up the process, the adviser said.

In Trump's first filing in the case, his attorney is now pushing back on the DA's motion -- which requested an Oct. 23 trial start date for all 19 defendants -- saying they oppose it.

"President Trump respectfully puts the Court on notice that he opposes the State's 'motion for entry of pretrial scheduling order' and 'motion to specially set trial,'" the filing states.

Trump attorney Steven Sadow also notified the court that they would be filing "a timely motion" to sever the case from Cheseboro -- who requested the speedy trial-- as well as any other defendant who "files such a demand."

"President Trump further respectfully puts the Court on notice that he requests the Court set a scheduling conference at its earliest convenience so he can be heard on the State's motions for entry of pretrial scheduling order and to specially set trial," the filing states.
