An immigration officer entered a plea of not guilty on Friday to federal charges alleging that he had mendaciously apprised the FBI of an assault upon his person prior to his shooting and wounding of a Venezuelan man amid the immigration crackdown in Minneapolis earlier this year.

Immigration and Customs Enforcement officer Christian Castro appeared before a U.S. magistrate judge after prosecutors indicted him this month on six federal counts of making false statements concerning the Jan. 14 shooting of Julio Cesar Sosa-Celis.

Clad in a black suit, an electronic monitor conspicuous at his ankle, Castro had precious little to say over the course of the hearing.

He had been suspended without pay by ICE earlier this year.

Castro’s federal hearing transpired but a day after his appearance in state court on assault charges and his subsequent release from custody.

His defense attorney, Daniel Gerdts, declined to comment on the case as he departed the courthouse Friday.

The court proceedings ensued subsequent to months of legal wrangling over whether Castro, 52, would be extradited from Texas, his home state, to answer charges in Minnesota.

He ultimately returned of his own volition after being released from a Texas jail the previous month.

The case was swiftly subsumed into the maelstrom of national politics.

Minnesota constitutes a perennial target of President Donald Trump, who routinely excoriates Democratic Gov. Tim Walz—a former vice-presidential candidate in the most recent presidential election—as well as Rep. Ilhan Omar, a native of Somalia.

Texas Gov. Greg Abbott, an ally of Trump, at junctures conflated his refusal to sign Castro's extradition warrant with ongoing investigations into pervasive fraud within Minnesota's government social service programs.

Trump invoked those fraud investigations as justification for the crackdown.

In the federal and state prosecutions of Castro alike, prosecutors allege that, while discharging his firearm through the front door of a Minneapolis residence, he struck 24-year-old Sosa-Celis in the leg.

They further contend that Castro subsequently deceived investigators by claiming he had been assailed with a broom handle and a snow shovel prior to firing his weapon.

Minnesota prosecutors indicted him in May, yet their endeavours to extradite him from Texas, where he had been apprehended, proved fruitless.

He ultimately surrendered himself to federal authorities after officials raised alarms that he might abscond across the U.S.-Mexico border upon release from a Texas jail.

He had been indicted separately in U.S. District Court earlier this month.

It constitutes the inaugural prosecution by the Justice Department of a federal officer for conduct perpetrated during this year's Operation Metro Surge, an initiative that deployed thousands of agents to the Twin Cities and precipitated sweeping protests, arrests, and the fatal shootings of two U.S. citizens by federal officers.

At a prior hearing convened before a federal judge in Texas, Castro was released on a $75,000 bond and mandated to wear a GPS ankle monitor.

He was further instructed to surrender both his passport and any personal firearms.

Minnesota authorities have engaged in a protracted contest with the Trump administration over who ought to adjudicate any charges against Castro.

The Department of Homeland Security has characterized Minnesota’s prosecution of Castro as “unlawful and nothing more than a political stunt,” asserting that jurisdiction is vested exclusively in federal authorities.

On May 29, Castro was apprehended in Texas by authorities—among them Minnesota’s Bureau of Criminal Apprehension—subsequent to a Minnesota judge’s issuance of a nationwide warrant.

Minnesota had sought his extradition throughout the period of his detention in Texas, yet Abbott declined to affix his signature to an extradition warrant.
