Jan. 3 (UPI) -- Former Milwaukee County (Wisc.) Judge Hannah Dugan resigned on Saturday following her federal felony conviction for obstruction of law enforcement in April.

Dugan, 66, submitted her resignation letter to Wisconsin Gov. Tony Evers on Saturday and said it is effective immediately.

"Behind the bench, I have presided over thousands and thousands of cases -- with a commitment to treat all persons with dignity and respect, to act justly, deliberatively and consistently, and to maintain a courtroom with the decorum and safety the public deserves," Dugan said in the resignation letter.

She said that she is the "subject of unprecedented federal legal proceedings" that "present immense and complex challenges that threaten the independence of our judiciary."

A federal jury found her guilty of obstruction last month for her effort to help an "undocumented immigrant" from Mexico elude Immigration and Customs Enforcement agents when they arrived at the county courthouse to arrest him.
