BALTIMORE, (AP) – Kilmar Abrego Garcia, whose arrest and fight to stay in the U.S. has become a flashpoint in President Donald Trump’s immigration crackdown, surrendered Monday morning to U.S. immigration authorities in Baltimore. He faces possible efforts by the Trump administration to deport him to Uganda.

The 30-year-old Salvadoran national was wrongfully deported in March to a notorious prison in his native El Salvador. He was returned to the U.S. in June, but only to face human smuggling charges that his lawyers call preposterous and vindictive.

The Trump administration has said it is trying to deport Abrego Garcia months before his trial is scheduled in Tennessee, alleging that the 30-year-old married father is a danger to the community and an MS-13 gang member. He denies the gang allegation, pleaded not guilty to smuggling charges and has asked a judge to dismiss the case on ground of vindictive prosecution. Immigration officials have said they plan to deport Abrego Garcia to Uganda after he declined an offer to be removed to Costa Rica in exchange for pleading guilty to the smuggling charges.
