Hunter Biden has arrived at the courthouse for Day 2 of his federal gun trial.

He was accompanied by wife, Melissa Cohen Biden.

His stepmother, first lady Jill Biden, and his half-sister Ashley Biden are also in attendance for the second day in a row.

Hunter Biden returns to court this morning for the start of arguments in his federal gun trial.

Attorneys with special counsel David Weiss' office and lawyers for Hunter Biden are both scheduled to deliver opening statements in the case.

Judge Maryellen Noreika yesterday swore in a jury of six men and six women, completing the jury selection process in a single day to put the trial two days ahead of schedule.

Hunter Biden spent the first day of his gun trial taking notes, reading documents placed in front of him by his attorneys, and often turning to catch a glimpse of the friends and family who came to court to support him.

At one point, he nodded along as a prospective juror spoke about her friend's overdose after addiction.

Jill Biden was seated behind Hunter Biden all day, and she watched attentively as some jurors told the court that they had such a skewed view of her family that they could not be impartial. The first lady did not appear to react in those moments, but at times her daughter Ashley Biden placed her hand on the first lady's back in support.

Hunter Biden's family members also appeared to be actively involved with his defense strategy -- at one point standing up and huddling with Hunter Biden's attorneys Abbe Lowell and David Kolansky after a sidebar.

When court was dismissed, Jill Biden gave Hunter Biden a hug and a kiss before he walked out hand-in-hand with his wife.

Hunter Biden and his stepmother, first lady Jill Biden, departed court at the conclusion of the day's jury selection proceedings.

With opening statements set for Tuesday, prosecutors said their first witness would be FBI Special Agent Erika Jensen, who will introduce into evidence several of Hunter Biden's text messages, as well as excerpts from his 2021 memoir, "Beautiful Things," and other evidence.

The parties had carved out three days to select a jury, which means the proceedings are currently running ahead of schedule.

Judge Maryellen Noreika told jurors they would likely need to be available for the trial through June 14, with the possibility of deliberations stretching into the week of June 17.

A member of the jury that found Hunter Biden guilty told ABC News after the verdict that the trial was a "waste of taxpayers' dollars."

"I just think he needs help. He needs rehab," the juror told ABC News regarding the defendant. "In my opinion, this is a waste of taxpayers' dollars. They should have fined him."

Asked what she thinks a fair sentence would be, the juror said, "I don't think that anyone who is a nonviolent drug addict should be in prison. Just fine him. We know he did something wrong. Just fine him. He needs help."

She said the jurors "worked together really well."

"Considering who his father is and the political climate in this country, it turned out better than I expected," she said. "There was no fighting in the jury room."

Judge Maryellen Noreika said before court ended that she would schedule a sentencing date in the next 120 days. Hunter Biden could face up to 25 years in prison, though legal experts believe he will not serve time as a first-time and nonviolent offender.
