A man who admitted to assaulting a federal immigration officer during protests outside a U.S. Immigration and Customs Enforcement facility in Portland, Oregon, has been sentenced to 30 months in federal prison, underscoring the Justice Department’s continued effort to prosecute violence directed at law enforcement officers.
Robert Jacob Hoopes received the sentence Thursday after previously pleading guilty to aggravated assault of a federal employee with a dangerous weapon.
According to court documents, the incident occurred during a protest outside an ICE facility in June 2025. Prosecutors said Hoopes threw a rock that struck an ICE Enforcement and Removal Operations officer in the face, causing serious injuries.
Federal authorities described the impact as significant. Court records indicate that the officer suffered a wound that bled heavily and impaired his vision. The injury was severe enough to require medical treatment beyond basic first aid.
The case has become another example of the tension that has surrounded demonstrations related to immigration enforcement, with federal officials drawing a distinction between lawful protest and acts of violence.
“Today’s message is clear — violence is not a protest,” U.S. Attorney for the District of Oregon Scott Bradford said following the sentencing.
“When you cross the line and assault a federal officer, you will be prosecuted,” Bradford added.
In addition to the prison term, Hoopes was ordered to serve three years of supervised release and pay more than $8,000 in restitution.
Federal investigators relied in part on facial recognition technology to identify Hoopes as a suspect. According to previously reported details, investigators obtained a photograph published by OregonLive.com and submitted the image to commercially available facial recognition software.
Authorities said the software generated roughly 30 potential matches from publicly available databases. Investigators then reviewed those results and ultimately focused on a photograph found on a Reed College SmugMug page titled “Canyon Day April ’23.”
Prosecutors said a tattoo visible on the individual in that image matched a tattoo observed on the suspect during the June protest, helping investigators confirm his identity.
The use of facial recognition technology in the investigation highlights the growing role of digital tools in modern law enforcement, particularly in cases involving large public gatherings where traditional identification methods can be more difficult.
Before sentencing, Hoopes’ father publicly defended aspects of his son’s character while declining to address the details of the criminal case.
Tom Hoopes described his son in an interview with KATU as a “lifelong Quaker who is deeply committed to pacifism.”
While acknowledging that his son attended the protest, he stopped short of discussing his specific actions that day.
“What his involvement was: I can’t speak to that, but he is deeply committed to justice,” Tom Hoopes told the outlet.
The Justice Department has pursued numerous prosecutions involving individuals accused of assaulting federal officers during demonstrations connected to President Donald Trump’s immigration policies.
Federal officials have emphasized that while Americans retain the right to protest government policies, attacks on law enforcement personnel will be treated as criminal conduct.
The sentencing also comes amid continued confrontations at immigration-related facilities across the country. More recently, demonstrations outside Delaney Hall, an immigration detention center in Newark, New Jersey, have led to dozens of arrests following clashes between protesters and law enforcement.
As debates over immigration policy continue, the Portland case serves as a reminder that political disagreements can quickly escalate into violence, leaving injured officers, criminal prosecutions, and lasting consequences that extend far beyond the original protest itself.
