Rep. Dan Schoen, DFL-Cottage Grove, said he will run for the seat being vacated by Sen. Katie Sieben, DFL-Newport, who announced Tuesday she will not run again. 

Schoen is a Cottage Grove Police patrol officer. The district is DFL leaning. 

"It's been an honor to serve (the district) in the House and i cant wait to serve the Senate district," Schoen said. "We'll do even more." 

Schoen, a key backer of the state's medical marijuana law, took a leave from police duties last summer to serve as a security consultant for Leafline Labs, one of two medical cannabis companies licensed in Minnesota.
