MILWAUKEE COUNTY, Wis. (CBS 58) -- Milwaukee County Judge Hannah Dugan, indicted by a federal grand jury, has filed a motion to dismiss the charges against her. 

The motion to dismiss claims Dugan is entitled to "judicial immunity" for her official acts.

The FBI claims Judge Dugan helped an undocumented immigrant, Eduardo Flores-Ruiz, try to escape immigration agents at the county courthouse. 

Judge Dugan is indicted on two counts -- one for "knowingly concealing" Flores-Ruiz, who had a warrant for his arrest. 

The other count accuses her of trying to influence, obstruct, or impede the arrest of Flores-Ruiz, and mentioned her alleged actions of telling agents they need a judicial warrant, telling agents to leave the hallway where the arrest was planned, and leading Flores-Ruiz and his lawyer through a non-public doorway.

Judge Dugan's attorney sent us a statement saying, "Judge Dugan asserts her innocence and looks forward to being vindicated in court."

Dugan is scheduled to be back in court Thursday, May 15.
