Two sheriff’s deputies and their supervisors have been disciplined on Colorado for sharing information with U.S. Immigration and Customs Enforcement (ICE), in violation of a new state law.

The state law, signed by Democrat Governor Jared Polis in May, “prohibits local government employees, including law enforcement, from sharing identifying information about people with federal immigration officials,” Fox News reported.

The Department of Justice has sued the state of Colorado, arguing that the policies violate the U.S. Constitution and federal immigration laws.

The incident unfolded on June 5, when Mesa County Sheriff’s Deputy Alexander Zwinck pulled over Caroline Dias-Goncalves, a 19-year-old Brazilian nursing student after she allegedly drove too close to a semi-truck. Dias-Goncalves was reportedly released with a warning after about 20 minutes, but ICE agents followed up and arrested her for an expired visa shortly thereafter.

Mesa County Sheriff Todd Rowell explained Thursday that Zwinck had shared her location and a description of her vehicle in a Signal group chat that included ICE agents. Dias-Goncalves was then “arrested by ICE and taken to a detention facility, where she was held for 15 days before being released on bond,” according to Rowell.

Colorado Attorney General Phil Weiser sued Zwinck last week for “blatant violation of state law.”

A second Mesa County deputy, Erik Olson, was also found to have shared immigration information with federal agents.

Zwinck was placed on three weeks of unpaid leave and Olson was placed on two weeks of unpaid leave, Rowell said.

Two supervisors were also disciplined, with one suspended without pay for two days and another receiving a letter of reprimand. A third supervisor received counseling.

“The Mesa County Sheriff’s Office should not have had any role in the chain of events leading to Miss Dias-Goncalves’ detention, and I regret that this occurred. I apologize to Miss Dias-Goncalves,” Rowell said.

Zwinck and Olson allegedly told officials that they believed they were following long-standing procedures, though an internal investigation found they had both received and read two emails about previous limits on cooperation with immigration officials.

During his disciplinary hearing, Zwinck reportedly said that “he was not aware of the new law nor was he interested in contributing to immigration enforcement.” Olson testified that sending information to federal agents during traffic stops was “standard practice.”

“It was routine for ICE to show up on the back end of a traffic stop to do their thing,” Olson stated. “I truly thought what we were doing was condoned by our supervision and lawful.”

Rowell told reporters that “drug task force members from other law enforcement agencies, including the Colorado State Patrol, had also shared information with immigration agents on the Signal chat, although the state patrol denied the accusation.”

The sheriff slammed Weiser for enforcing laws “selectively” and called on the attorney general to drop the lawsuit.

“As it stands, the lawsuit filed by the Attorney General’s Office sends a demoralizing message to law enforcement officers across Colorado—that the law may be wielded selectively and publicly for maximum political effect rather than applied fairly and consistently,” he said.

A spokesperson for Weiser said there was evidence of a “blatant violation of state law” and the AG had to act.

“The attorney general has a duty to enforce state laws and protect Coloradans, and he’ll continue to do so,” spokesperson Lawrence Pacheco told Fox News.

The U.S. Department of Justice has amended its complaint against the state of Colorado and the city of Denver over “sanctuary” policies.

The Justice Department’s lawsuit, initially filed in May, was recently amended to address Weiser’s lawsuit against Zwinck.

“When officers choose to cooperate with federal immigration enforcement agents to keep their communities safe and enforce federal law, the State of Colorado hauls them into court as punishment for doing their jobs,” the lawsuit now states.

The defendants named in the DOJ lawsuit include Gov. Polis, AG Weiser, the Denver City Council, Denver Mayor Mike Johnston, the Denver Sheriff’s Department, and Denver Sheriff Elias Diggins.
