A coffin arrived in Detroit from Iraq on Friday with the remains of 41-year-old Jimmy Aldaoud, whose death this month prompted bipartisan efforts to curb the Trump administration’s deportation of Iraqi nationals.

Mr. Aldaoud, whose parents were Iraqi, was born in a refugee camp in Greece, entered the United States legally in 1979 when he was 6 months old and grew up in the Detroit area.

His life was unsettled: He battled depression and diabetes and also had bipolar disorder and schizophrenia. He was in and out of jail, with at least 20 criminal convictions over the past two decades, according to Immigration and Customs Enforcement officials.

After being arrested on a larceny charge, he was deported to Iraq on June 2 with very little insulin, no money and no knowledge of Arabic. His sisters did not know he had been deported until he called from the city of Najaf.
