The Maryland construction worker became the face of President Donald Trump’s hardline immigration policies when he was wrongfully deported.

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.

The Trump administration took him into immigration custody Monday morning after he was released from criminal custody on Friday.
