The letter was sent Saturday. Republicans had been making plans to impeach her ever since her Dec. 19 conviction. A spokesperson for Gov. Tony Evers, a Democrat, said his office received Dugan's letter, and he would work to fill the vacancy without delay.
“As you know, I am the subject of unprecedented federal legal proceedings, which are far from concluded but which present immense and complex challenges that threaten the independence of our judiciary. I am pursuing this fight for myself and for our independent judiciary,” Dugan said in her letter.
Last April, federal prosecutors accused Dugan of distracting federal officers trying to arrest a Mexican illegal immigrant outside her courtroom and leading the man out through a private door. A federal jury convicted her of felony obstruction.
On April 18, immigration officers went to the Milwaukee County courthouse after learning 31-year-old Eduardo Flores-Ruiz had reentered the country illegally and was scheduled to appear before Dugan for a hearing in a state battery case.
Dugan confronted agents outside her courtroom and directed them to the office of her boss, Milwaukee County Chief Judge Carl Ashley, because she told them their administrative warrant wasn’t sufficient grounds to arrest Flores-Ruiz.
After the agents left, she led Flores-Ruiz and his attorney out a private jury door. Agents spotted Flores-Ruiz in the corridor, followed him outside and arrested him after a foot chase. The U.S. Department of Homeland Security announced in November he had been deported.
Republican Wisconsin Assembly Speaker Robin Vos praised Dugan's decision.
“I’m glad Dugan did the right thing by resigning and followed the clear direction from the Wisconsin Constitution," Vos said.
