ST. PAUL — A Democratic legislator has resigned from a paid fellowship at the University of Minnesota amid questions over how he got the post, and the former Democratic lawmaker who hired him has been reassigned.

Rep. Jamie Long, a freshman lawmaker from Minneapolis who serves as vice chairman of an energy and climate committee, was hired in July as an “energy research project specialist” at the university’s Institute on the Environment. He resigned this week. He was hired by former state Sen. Ellen Anderson, of St. Paul. She was executive director of the institute’s Energy Transition Lab until Tuesday, when the university says she was reassigned to work on other projects, the St. Paul Pioneer Press reported Thursday.
