Kilmar Abrego Garcia, the Maryland man who was unlawfully deported to El Salvador earlier this year, will gather with members of his family, immigration activists, community leaders and elected officials at a rally in Baltimore on Monday morning as the Trump administration warns it could send him to Uganda as soon as this week.

Immigration officials have said they plan to deport Abrego Garcia to Uganda, which recently agreed to a deal to accept certain deportees from the U.S.

Here’s what’s new in the Abrego Garcia’s case, and what’s expected Monday morning as he arrives at the ICE Field Office in Baltimore.
