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.

Gun store clerk Gordon Cleveland testified that he watched from "about two feet" away as Hunter Biden, in the course of purchasing a handgun in 2018, filled out Form 4473 and checked the box asking applicants whether they were active drug users.

After Hunter Biden selected the Colt Cobra for purchase, Cleveland said he asked him to fill out Form 4473, which he told him was required for "every gun purchase." Cleveland testified that he instructed Hunter Biden to write in his personal information and answer the questions below, "and to take your time answering them," he said.

Cleveland testified that he watched as Hunter Biden answered several questions on the form before he approached question 11.E., which asked about drug use.

"You saw him strike that box with an 'X'?" prosecutor Derek Hines asked.

"Yes," Cleveland said.

"He didn't seem to express any confusion by that question?" Hines asked.

"No," Cleveland said.
