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."

Prosecutor Leo Wise used witness testimony and Hunter Biden's own words from his memoir and text messages to argue that the president's son "knew exactly what he was doing" when prosecutors say he falsely claimed he was not addicted to drugs in order to purchase a Colt handgun in 2018.

"Take the defendant's word for it," Wise said as he showed the jury excerpts from Hunter Biden's book that described his drug use and addiction.

Wise, showing the jurors a side-by-side comparison of testimony regarding his truck from his daughter Naomi Biden and then-girlfriend Hallie Biden, said their testimony is "circumstantial evidence " that shows "the defendant used crack in the truck" days after purchasing the firearm.

Naomi Biden testified that she returned the truck to her father "clean" on Oct. 19, 2018, and Hallie Biden testified that a few days later she found Hunter Biden's gun in the vehicle along with drug paraphernalia and drug remnants.

Wise also showed the jury a calendar of the month of October 2018 that showed the cash withdrawals made by Hunter Biden. "None of the cash was for rehab," Wise said.

The evidence, Wise told jurors in conclusion, "supports only one verdict."

Hunter Biden's attorney Abbe Lowell then began his closing arguments.
