Former Sen. Feingold will be a professor at Marquette Law School

MILWAUKEE — Former U.S. Sen. Russ Feingold is moving from politics to the world of academia.

Marquette University Law School says Feingold will be a visiting professor of law starting in the spring semester.

The Milwaukee school said Wednesday that the three-term Democratic senator will teach an elective course called Current Legal Issues: The U.S. Senate. It will be open to upper-level law students.

Feingold’s third term in the Senate ended Monday. His replacement is Ron Johnson, a Republican businessman from Oshkosh set to be sworn in Wednesday.

Feingold earned his undergraduate degree from the University of Wisconsin-Madison and his law degree from Harvard University. He practiced law for six years with two Wisconsin law firms and also served for 10 years in the state Senate.
