Kilmar Abrego Garcia, whose mistaken deportation has become a flashpoint in President Donald Trump’s immigration crackdown, pleaded not guilty Friday to human smuggling charges in a federal court in Tennessee.

The hearing was the first chance the Maryland construction worker has had in a U.S. courtroom to answer the Trump administration’s allegations since he was mistakenly deported in March to a notorious prison in El Salvador.

Abrego Garcia’s attorneys have characterized the smuggling case as a desperate attempt to justify the mistaken deportation. The investigation was launched weeks after the U.S. government deported Abrego Garcia and following a Supreme Court order and mounting pressure to return him.

Abrego Garcia’s lawyers told a judge Friday that some government witnesses cooperated to get favors regarding their immigration status or criminal charges they were facing. A federal agent acknowledged during his testimony that one witness was living in the U.S. illegally with a criminal record and is now getting preferred status.

“He sounds like the exact type of person this government should be trying to deport,” Federal Public Defender Dumaka Shabazz said. “They’re going to give all these other people deals to stay in the country just to get this one other person.”

Most of Friday’s hearing focused on whether Abrego Garcia should be released as he awaits trial. U.S. Magistrate Judge Barbara Holmes said she will write her decision “sooner rather than later.”

The smuggling charges stem from a 2022 traffic stop for speeding in Tennessee during which Abrego Garcia was driving a vehicle with nine passengers. While officers suspected possible smuggling, Abrego Garcia was allowed to go on his way with only a warning.

Body camera footage shows a calm exchange between officers and Abrego Garcia. The officers then discussed among themselves their suspicions of smuggling before letting him go. One of the officers says, “He’s hauling these people for money.” Another says Abrego Garcia had $1,400 in an envelope.

The federal indictment accuses Abrego Garcia of smuggling throughout the U.S. hundreds of people living in the country illegally, including children and members of the violent MS-13 gang.

In briefings before Friday’s hearing, U.S. attorneys described Abrego Garcia as a danger to the community and a flight risk. They also accused him of trafficking drugs and firearms and of abusing the women he transported, among other claims, although he is not charged with such crimes.

Rob McGuire, Acting U.S. Attorney for the Middle District of Tennessee, told the judge Friday that “migrant transportation is inherently dangerous.”

The prosecutor also presented two orders of protection that Abrego Garcia’s wife sought in 2020 and 2021 against him for domestic violence. Jennifer Vasquez Sura said this spring that the couple had worked things out “privately as a family, including by going to counseling.”

Abrego Garcia’s attorneys rejected the prosecution’s assertions that he was a danger, while arguing the charges aren’t serious enough for detention.
