Hunter Biden, the son of US President Joe Biden, has been found guilty of three gun charges that could see him jailed.
A federal court jury in the Bidens' home state of Delaware reached a verdict after three hours of deliberations over two days.
They found Hunter Biden guilty of lying on a form when he bought a Colt revolver in 2018, and illegally possessing the weapon for 11 days. Hunter Biden had declared on the form that he was not using illegal drugs when in fact he was a crack cocaine user.
It's the second guilty verdict to rock the US election campaign in two weeks after Donald Trump was convicted of 34 counts of falsifying business records relating to a "hush money" payment to porn star Stormy Daniels.
Hunter Biden's lawyer, Abbe Lowell, said they would "vigorously pursue all the legal challenges available to Hunter".
The federal charges have a maximum prison sentence of 25 years, but legal experts say Hunter Biden is unlikely to receive close to the maximum as a first-time offender, and probation is a more likely outcome than prison.
A sentencing date is yet to be set, but it's likely to be before the election on November 5.
The White House confirmed Joe Biden was planning to travel to Wilmington, Delaware, to spend the evening with his son.
The president spoke at a gun safety event in Washington DC a few hours after the verdict but did not address his son's conviction. A routine press conference at the White House, scheduled for about the same time, was cancelled.
