Dugan was arrested and charged with obstruction of an official proceeding on Friday after evidence came to light that she had shielded an illegal immigrant from federal agents, according to a criminal complaint. She was also charged with concealing an individual to prevent discovery and arrest.

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.

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.
