A former government attorney who drew national attention after a tense courtroom exchange over immigration enforcement last month is launching a bid for Congress against Rep. Ilhan Omar (D-MN).

Julie Le, who previously defended Immigration and Customs Enforcement actions in Minnesota as a temporary attorney for the Justice Department, announced Wednesday that she is running as a Democrat in Minnesota’s 5th Congressional District. She plans to launch her campaign Saturday in the Minneapolis suburb of Brooklyn Park, according to her campaign website.
