Kilmar Abrego Garcia plans to travel to Maryland before returning to Tennessee in January for his criminal trial.

The government of Costa Rica is willing to accept Kilmar Abrego Garcia "upon the conclusion of any criminal sentence he may serve in the U.S.," according to a letter obtained by ABC News. The Salvadoran native was released from criminal custody in Tennessee on Friday and is on his way to Maryland, an attorney told ABC News.

The filing took aim at comments last week in which the homeland security secretary “assailed Mr. Abrego’s character and reputation," his attorney said.
