The mayor of Portland, Oregon, demanded U.S. Immigration and Customs Enforcement leave his city after federal agents launched tear gas at a crowd of demonstrators — including young children — outside an ICE facility during a weekend protest that he and others characterized as peaceful.

Thousands of people attended the “ICE out” protest on Saturday in South Portland, according to the Portland Police Bureau. The protest began near Elizabeth Caruthers Park, and demonstrators later moved to an ICE facility a few blocks away, CBS affiliate KOIN reported. That’s where witnesses said agents deployed tear gas, pepper balls and rubber bullets.

Erin Hoover Barnett, a former OregonLive reporter who joined the protest, said she was about 100 yards from the building in Portland’s South Waterfront when “what looked like two guys with rocket launchers” started dousing the crowd with gas.

“To be among parents frantically trying to tend to little children in strollers, people using motorized carts trying to navigate as the rest of us staggered in retreat, unsure of how to get to safety, was terrifying,” Barnett wrote in an email to OregonLive.

The use of tear gas continued intermittently through the night as the group of protesters dwindled, KOIN reported.

The federal government “must, and will, be held accountable,” Portland Mayor Keith Wilson said Saturday night. “To those who continue to make these sickening decisions, go home, look in a mirror, and ask yourselves why you have gassed children.

Wilson also said the city would be imposing a fee on detention facilities that use chemical agents.

The mayor said the daytime demonstration was peaceful, “where the vast majority of those present violated no laws, made no threat and posed no danger” to federal agents.

“To those who continue to work for ICE: Resign. To those who control this facility: Leave,” Wilson wrote in his statement Saturday night. “Through your use of violence and the trampling of the Constitution, you have lost all legitimacy and replaced it with shame.”

The Portland Fire Bureau sent paramedics to treat people at the scene, police said. Police officers monitored the crowd but made no arrests on Saturday.

In a statement posted Sunday to social media, Oregon Gov. Tina Kotek condemned the presence of ICE in the state. 

“Trump’s ICE has no place in Oregon,” Kotek wrote. “The use of tear gas against families, children, and peaceful demonstrators yesterday is a horrific abuse of authority that undermines public safety and violates constitutional rights. Federal agents must stand down and be held accountable.”

The Portland protest was one of many similar demonstrations nationwide against the Trump administration’s immigration crackdown in cities like Minneapolis, where in recent weeks federal agents killed two residents, Alex Pretti and Renee Good.

In downtown Los Angeles, federal officers also deployed tear gas into the crowd on Saturday after local police issued an unlawful assembly order, CBS LA reported. At least eight people were arrested, according to the Los Angeles Police Department.

Federal agents in Eugene, Oregon, deployed tear gas on Friday when protesters tried to get inside the Federal Building near downtown. City police declared a riot and ordered the crowd to disperse.

President Trump posted Saturday on social media that it was up to local law enforcement agencies to police protests in their cities. However, Mr. Trump said he has instructed Homeland Security Secretary Kristi Noem to have federal agents be vigilant in guarding U.S. government facilities.

“Please be aware that I have instructed ICE and/or Border Patrol to be very forceful in this protection of Federal Government Property. There will be no spitting in the faces of our Officers, there will be no punching or kicking the headlights of our cars, and there will be no rock or brick throwing at our vehicles, or at our Patriot Warriors,” Mr. Trump wrote. “If there is, those people will suffer an equal, or more, consequence.”

The Oregon Ducks have accomplished just about everything possible for a college football team in the last few seasons. They’ve had an undefeated regular season, notched back-to-back College Football Playoff appearances and won a ton of bowl games.

The Ducks have been transformed into a perennial contender, and the only thing still on their agenda is the elusive national championship victory. They’ve gotten closer to reaching that goal in each of Dan Lanning’s first four seasons as head coach, so it feels like just a matter of time.

The college football staff of The Athletic were polled on a wide range of predictions about next season, and the most eye-popping result was next season’s national championship game winner, with Oregon receiving the most votes. Nine people out of 28 votes for them, which may not seem too convincing, but the next closest team was the Notre Dame Fighting Irish with five votes.

The Ducks had their season ended by the Indiana Hoosiers, who went on to win the national championship. However, star quarterback Fernando Mendoza declared for the NFL Draft after the historic victory, so that could be enough to put Oregon in the driver’s seat.
