Rhodes, 24, who received funding from George Soros as part of the Antifa Portland Resistance group, was found guilty by a Washington County Circuit Court jury on Friday.
The girl’s personal details have been withheld to respect her privacy. The jury’s 10-2 verdict came after a 1.5-day trial, according to reports.
Rhodes will be sentenced in May, however he is also scheduled next week to go to trial in Multnomah County Circuit Court in a separate case relating to sex with an underage boy.
Court papers say Rhodes groomed the boy on the internet and the boy wasn’t able to consent because of his age.
Rhodes faces four counts of second-degree sexual abuse and one count of third-degree sexual abuse.
The Antifa leader was on supervision by the Oregon Youth Authority for sexual abuse and sodomy at the time he was charged for alleged abuse in both counties, authorities say. Juvenile records aren’t public, so details of the earlier case aren’t available.
Rhodes had been required to register as a sex offender at the time he was charged in the Multnomah and Washington county cases, however that didn’t stop Antifa from allowing him to work closely with underage boys and girls.
It also didn’t stop George Soros from pumping millions of dollars into the movement.
As an Antifa leader, Rhodes was frequently seen at marches and sitting in on meetings at Portland City Hall. He also was a leader of Portland’s Resistance, a group that formed after Donald Trump won the presidential election in November 2016.
He helped organize people during night after night of violent and destructive protests immediately after Trump’s victory.
Rhodes is facing as many as five years in prison for the statutory rape of the underage girl if the prosecution successfully argues that Rhodes’ felony was particularly egregious. The court case regarding the accusations of rape of an underage boy begin next week.
