9:08 AM PT -- President Biden just addressed the conviction, saying in part ... "So many families who have had loved ones battle addiction understand the feeling of pride seeing someone you love come out the other side and be so strong and resilient in recovery."

He adds, "As I also said last week, I will accept the outcome of this case and will continue to respect the judicial process as Hunter considers an appeal."

8:56 AM PT -- Hunter Biden just walked out of court after being found guilty in his gun case -- and he was holding his wife and Jill Biden's hands ... and he seemed to be in relatively good spirits. A sentencing date hasn't been set -- but the judge reportedly noted sentencing typically goes down about 120 days after a verdict is rendered.

If they follow that timetable, that would put HB's sentencing date in October ... not long before the election.

Hunter Biden has learned his fate in his federal gun case ... and a jury of his peers was convinced he committed the crimes.

President Biden's son was just found guilty on all 3 felony counts of lying on a federal firearms application. The lies were about his drug use. The jury only deliberated for 3 hours before convicting Hunter.

Hunter was accused of filling out a form to purchase a revolver back in October 2018, certifying he was NOT a user of or addicted to any controlled substance.

He had pled not guilty, and his trial had plenty of juicy testimony.

As we reported ... Hunter's ex-girlfriend, Zoe Kestan, took the stand last week and told the jury about his drug days ... testifying Hunter would smoke crack as soon as he woke up, at least in 2018 when they were together.

Hunter's ex claimed she saw him using drugs in September 2018, only weeks before he bought the gun ... which was the crux of the case.

He faces up to a 25-year prison sentence, but will likely serve only a fraction of that time ... if any, because it's his first conviction of any type. Of course, Hunter's father could technically pardon him from the federal conviction, but has already said he will not do that.

Hunter's trial follows Donald Trump's historic felony conviction ... and like Trump, Hunter did not testify in court.
