In recent weeks, immigration officers have arrested several people in the halls of the Milwaukee County Courthouse. Here's what we know about Dugan's arrest and the circumstances leading up to it.

Hannah Dugan, the Milwaukee County judge arrested Friday by the FBI for allegedly obstructing federal authorities who were seeking to detain an undocumented immigrant, was a longtime social justice advocate before she took the bench.

FBI Director Kash Patel said Milwaukee County Circuit Judge Hannah Dugan "intentionally misdirected federal agents away" from an immigrant who is in the U.S. illegally and was set to be arrested. Patel said that the man, Eduardo Flores-Ruiz, was later arrested and is currently being detained.
