Portland, OR. — A Portland man has pleaded guilty to assaulting a federal officer at the U.S. Immigration and Customs Enforcement office in South Portland.
Robert Jacob Hoopes, 25, pleaded guilty to aggravated assault of a federal employee with a dangerous weapon resulting in bodily injury.
According to court documents, on June 14, 2025, Hoopes threw a large rock that struck an officer with U.S. Immigration and Customs Enforcement in the head, causing a significant laceration over the officer’s eye. Later that day, Hoopes and two other individuals were seen using an upended stop sign as a makeshift battering ram, causing significant damage to the building’s main entry door.
On Aug. 5, 2025, a federal grand jury in Portland returned a two-count indictment charging Hoopes with aggravated assault on a federal employee with a dangerous weapon and depredation of federal property.
Hoopes faces a maximum sentence of 20 years in prison, a $250,000 fine, and three years of supervised release. He is scheduled to be sentenced May 12, 2026, before a U.S. District Court judge.
As part of his plea agreement, Hoopes agreed to pay full restitution, estimated at more than $7,000.
The case was investigated by the Federal Bureau of Investigation and is being prosecuted by the U.S. Attorney’s Office.

Finally holding people accountable for their actions. Common sense would tell us if people respected each other and the rule of law, complied and exercised the right of peaceful protesting while acknowledging that law enforcement has a job to do as well regardless of whether you agree with it or not.
