President Joe Biden hugged his son and spent several minutes with him on the tarmac at Delaware Air National Guard Base, hours after Hunter Biden was convicted in court.

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.

Judge Maryellen Noreika has so far quizzed more than 50 Delaware residents about their fitness to serve as jurors in the first trial of a sitting president's son. And being Delaware -- a small state that Joe Biden represented in the Senate for more than three decades -- nearly all of them had some level of familiarity with Hunter Biden's legal travails.

"I live in Delaware," one prospective juror said. "You can't swing a cat without hearing something."

"Delaware is a small place," another said. "So you hear stuff."

Several jurors said they had heard or read about this trial specifically. Most had only a cursory understanding of the case, but others expressed a detailed accounting of the charges. A few jurors mentioned the ill-fated plea deal that Hunter Biden initially struck with prosecutors last summer.

"At one time there was a deal, and then there wasn't," one man said.

One woman had even read Hunter Biden's memoir, "Beautiful Things," which prosecutors plan to use to help prove their case. She was excused by the judge.

President Joe Biden has emerged repeatedly in questioning, with prospective jurors expressing both positive and negative feelings on his presidency. One woman said she believed that Hunter Biden was facing charges largely because his father is the president.

"I think it was a very strong factor," she said.

Several others have been dismissed for harboring negative views toward the Bidens. Asked for his opinion about the president, one man said, "Not a good one." Another man said, "Negative toward the defendant." Both were excused.

The jury questionnaire also includes several questions about drug and alcohol addiction -- an affliction that many prospective jurors said has personally affected them.

One woman held back tears as she described how her best friend had died of a heroine overdose. Another man said his daughter is a recovering addict.

"Everybody needs a second chance," he said.

Judge Noreika has been pressing ahead, intent on getting a jury seated as soon as possible -- perhaps even by the end of the day.

In addition first lady Jill Biden and Hunter Biden's wife Melissa, his half-sister Ashley Biden attended court during the morning session, and his confidant and financier Kevin Morris is also in attendance.
