A juror in Hunter Biden's gun trial told ABC News that he did not know who Hunter Biden was before the trial started, and that his proximity to power made no difference to the jury.

"Everyone is human and everyone makes mistakes," the juror said. "And those mistakes can have serious consequences -- not just for them, but for everyone else."

The juror -- whose father was killed by gunfire when he was young -- said prosecutors successfully showed that Hunter Biden's drug use around the time of his gun purchase was "too close for me to consider him not a user or addict at that point."

"There's too many patterns that I can see that showed that he was using it when he purchased the gun," the juror said.

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.

In dramatic testimony, Hunter Biden's former romantic partner Hallie Biden described how, on the morning of Oct. 23, 2018, she went to go "clean out" Hunter Biden's car and found a gun.

"What did you find, in addition to trash and clothes?" prosecutor Leo Wise asked her.

"Remnants of crack cocaine and some paraphernalia," Hallie recounted. "Oh and the gun, obviously."

Hallie Biden said she found the firearm in "the arm console" of the car, which she said was not locked because "the lock had been broken." She said it was the first time she had ever seen a gun. She also found ammunition.

"I panicked, I wanted to get rid of them," she told the jury.

Asked why she panicked, Hallie Biden said she "didn't want him to hurt himself." She said she also worried about her kids finding the gun, saying she considered "hiding" it somewhere but was worried they would find it.

She said those frantic moments led to her throwing the gun in the trash. She told the jury she found a pouch to put it in -- which authorities say later tested positive for having cocaine on it -- and put the gun inside. The jurors were then shown the brown pouch she used.

"I was afraid to kind of touch it, I didn't know if it was loaded," Hallie Biden said, telling jurors she then put the pouch into another bag.

"I took it to the grocery store up the road and I threw it away," she testified.

At this point, jurors were shown surveillance video from the grocery store showing Hallie Biden throwing the gun into the trash.

In the video, her car is seen pulling into the parking lot; she then gets out of the driver's seated, opens the back door to get out the gun, then walks over to the store and places the bag in a garbage receptacle.

"Is that you Mrs. Biden?" prosecutor Leo Wise asked about her image on the video. "Yes," she replied.

Hunter Biden, sitting at the defense table, appeared to be locked on Hallie Biden the entire time, his head resting in his hand. He periodically covered his mouth.
