The Trump administration’s criminal investigation into Rep. Ilhan Omar (D-MN) is aimed at seeking to build a basis to strip the congresswoman of her U.S. citizenship and deport her, according to a new report.

Omar has been the subject of government investigations for months. President Donald Trump said in January that the Department of Justice is investigating Omar over discrepancies in her financial records. Vice President JD Vance later revealed that the DOJ is also probing allegations that Omar participated in a sham marriage with her biological brother from Somalia so he could gain residency in the United States.
