During the Obama administration, the FBI and Department of Homeland Security conducted an investigation in 2016 into whether Rep. Ilhan Omar entered into a sham marriage in 2009 with Ahmed Nur Said Elmi, a man believed to be her brother, to secure a green card.
Federal authorities found some evidence of marriage fraud, but prosecutors declined to bring charges because the five-year statute of limitations had expired. A U.S. Attorney appointed by Joe Biden reportedly closed the probe in 2021.
