A member of the jury in Hunter Biden's gun case told ABC News that "politics never came into play" in deliberations and that "the verdict absolutely was not politically motivated."

The juror said "it wasn't that hard" to reach a verdict, but said the panel of 12 had to overcome a six-six vote on yesterday afternoon when deliberations began.

When jurors returned this morning and deliberated further, he said they determined that prosecutors had met their burden of proof.

"If you're an addict, you're an addict," he said.

The juror said evidence that placed Hunter Biden at a 7/11 convenience store -- a place where he repeatedly said in his memoir and in text messages that he purchased drugs -- days prior to his gun purchase tipped them over the top.

A senior official who has been briefed on the matter tells ABC News that the Secret Service has not started planning for the possibility that Hunter Biden could be sentenced to prison. Those discussions with the Bureau of Prisons will start now.

As the son of a president, Hunter Biden gets Secret Service protection but can opt out of that protection if he wants.

As of now, he continues to have USSS protection and, for as long as his father is president, that would continue, even in prison, unless he waives the privilege.

When sentenced, he could face up to 25 years in prison -- though legal experts believe he will not serve time as a first-time and nonviolent offender.

President Joe Biden's schedule has been updated and he will now travel to Wilmington, Delaware, on Tuesday afternoon.

The president was originally scheduled to remain in Washington, D.C., but will instead head to Wilmington where he makes his home and where his son's trial just concluded.

Special counsel David Weiss, whose office prosecuted Hunter Biden, said following the verdict that Hunter Biden should be held no more accountable than any other citizen regarding the charges.

Weiss said while much of the testimony in the case was about Hunter Biden's abuse of drugs and alcohol, "Ultimately this case was not just about addiction, a disease that haunts families across the United States including Hunter Biden's."

This case was about "illegal choices [the] defendant made while in the throes of addiction, his choice to lie on a government form when he bought a gun, and the choice to possess that gun," he said.

It was also about "the rule of law," Weiss said. "No one in this country is above the law," he said.

Weiss, a Trump appointee, thanked Attorney General Merrick Garland for "ensuring that we have the independence to appropriately pursue our investigations and prosecutions."

Chemist Jason Brewer, testifying as an expert witness for the prosecution, told the jury that a brown leather pouch that contained Hunter Biden's gun at the time the weapon was retrieved by authorities tested positive for cocaine.

Brewer said there were "minimal amounts of white powder" on two locations on the pouch, which he combined and tested.

On cross-examination, Hunter Biden's attorney sought to raise doubts about how that white powder got there and who put it there -- emphasizing it could have been old, dating back to before Hunter Biden purchased the gun.

"You can't date when it got there?" defense attorney David Kolansky asked.

"I cannot," Brewer said.

Kolansky also emphasized that five years went by from the time the pouch was collected in October 2018 to when it was tested in October 2023 -- after the indictment in this case was already filed.

He emphasized the importance of the "chain of command," which Brewer conceded was "very important."

Earlier, Hunter Biden's former girlfriend Hallie Biden testified that she put the gun in the pouch, which she found in Hunter Biden's vehicle, after she discovered the weapon in the vehicle and before she disposed of it in a trash container.
