The 12-person jury found the US president's son lied about his drug use on a form when purchasing a handgun in 2018.

Biden now faces a possible prison term of up to 25 years, although a sentence of that length for a first-time offender is highly unlikely.

The jury deliberated after listening to a week of witness testimony about the 54-year-old's drug addiction.

He had pleaded not guilty to the charges - two counts of making false statements and one count of illegal gun possession.

The high-profile trial comes as his father runs for re-election. It is the first time a sitting president's child has been found guilty of a crime

President Joseph R. Biden said he would "accept the outcome of this case and will continue to respect the judicial process as Hunter considers an appeal"
