Kilmar Abrego Garcia, who was deported to El Salvador in March and returned to the United States in June to face human smuggling charges he denies, is alleging that the Trump administration is pressuring him to plead guilty by threatening to deport him to Uganda.

In a court filing on Saturday, Abrego’s attorneys said the Justice Department is urging him to accept a plea deal on two felony counts, with the promise that he would be deported to Costa Rica — where he would not face imprisonment — after serving any sentence, POLITICO reported.

“In conjunction with that proposal, the government produced a letter to Mr. Abrego’s counsel confirming that he could live freely in that country, which would accept him as a refugee or grant him residency status, and promise not to refoul him to El Salvador,” Abrego’s lawyers argued in court papers.

After Abrego rejected the proposal, Immigration and Customs Enforcement officials informed his attorneys that the government had decided instead to deport him to Uganda. They added that the option of deportation to Costa Rica would remain available only if he agreed to plead guilty by Monday, according to the filing.

“There can be only one interpretation of these events: the DOJ, DHS, and ICE are using their collective powers to force Mr. Abrego to choose between a guilty plea followed by relative safety, or rendition to Uganda, where his safety and liberty would be under threat,” Abrego’s attorney Sean Hecker wrote in the filing, per POLITICO.

The claims by Abrego’s attorneys were filed a day after his release from a Tennessee jail, where he had been held since returning to the United States in June. According to the filing, he has been ordered to report to an Immigration and Customs Enforcement field office in Baltimore on Monday morning.

Earlier this week, the Ugandan government announced it had reached an agreement with the Trump administration to accept third-country deportees from the United States. Uganda’s foreign minister said the arrangement would exclude individuals with criminal records and unaccompanied minors, while prioritizing deportees originally from African nations.

Garcia is asking a federal judge in Tennessee to dismiss the criminal case against him, arguing that the human smuggling charges stem from what he describes as a politically motivated effort by the Trump administration to punish him.
