A federal jury has convicted Hunter Biden, the son of US President Joe Biden, on all three felony charges in his federal gun trial.

Hunter Biden is charged with two felony counts of making a false statement related to the purchase of a firearm, and a third felony count of illegally possessing a gun while being an unlawful user of drugs.

Hunter Biden showed little emotion as the guilty verdicts were read out, and stared ahead with his arms folded before turning around to give a hug to some of the younger associates of his legal team.

Once court was adjourned, he stood and gave a hug to attorney Abbe Lowell before kissing and embracing his wife.

The pair walked out quietly together. He was promptly escorted out by Secret Service agents as journalists sprinted down staircases to get outside.

According to South Texas College of Law Houston professor Dru Stevenson, there’s a “50/50 chance” that Hunter Biden goes to prison after his guilty verdict on three felony charges.

“It’s hard to predict, but I think it’s very possible,” he says.

His logic: The judge on the case hasn’t given Biden’s lawyers “any breaks”.

Stevenson says that judge Maryellen Noreika was tough on Biden’s lawyers during evidentiary hearings, where she frequently ruled against defence lawyers’ requests.

The other possible scenario, professor Stevenson adds, is that Biden is sentenced to probation. The lighter sentencing seems likely due to Biden’s apparent rehabilitated state, he says.

If he is sent to prison, it’s not likely he would receive the entire 25 year maximum sentence, but would be more likely to be sentenced to around 20 months in prison, South Texas College of Law Houston professor Dru Stevenson says.

For that charge alone, the technical maximum penalty is 10 years. However, professor Stevenson says he’s only seen people receive five years for the charge.

“And that’s for people that were really dangerous, like someone who had already been on the FBI’s watchlist,” he says.

If Biden were to receive anything in the five- to 10-year range, “that would be bizarre and unprecedented”.
