A man previously found guilty of attacking a federal officer during protests at a U.S. Immigration and Customs Enforcement (ICE) site in Portland, Oregon, has been sentenced to 30 months in federal prison. The sentencing occurred on Thursday.

Robert Jacob Hoopes had earlier pleaded guilty to the charge of aggravated assault of a federal employee using a dangerous weapon. Court records reveal that during a protest in June 2025, Hoopes hurled a rock that struck an ICE Enforcement and Removal Operations officer in the face. This attack caused a significant injury.

“Today’s message is clear — violence is not a protest,” stated U.S. Attorney for the District of Oregon, Scott Bradford. “When you cross the line and assault a federal officer, you will be prosecuted.”

In addition to the prison term, Hoopes faces three years of supervised release and must pay restitution exceeding $8,000.

According to information previously shared by Fox News Digital, FBI investigators used facial recognition technology to identify Hoopes. A photograph from OregonLive.com was input into the software, generating about 30 potential matches from public databases. A match was confirmed through a photograph on a Reed College SmugMug page titled “Canyon Day April ’23,” which showed a tattoo matching the one seen on the protest participant.

Hoopes’ father, Tom Hoopes, described his son as a devoted Quaker with a firm belief in pacifism during an interview with KATU. He acknowledged his son’s presence at the protest but declined to elaborate on his exact role, noting his son’s commitment to justice.

The Justice Department has targeted numerous individuals accused of attacking federal officers during protests related to former President Donald Trump’s immigration measures. The protests have led to multiple arrests, with clashes also arising at other locations such as Newark’s Delaney Hall detention center in New Jersey, resulting in further detentions.
