Igo was elected to the Minnesota House of Representatives in 2020 and was reelected in 2022. He first ran after two-term Republican incumbent Sandy Layman announced that she would not seek reelection.[4] Following 2022 legislative redistricting, he was drawn into the same area as DFL Representative Julie Sandstede, whom he defeated in the general election.[5][6]
Igo serves as an assistant minority leader for the House Republican caucus and sits on the Climate and Energy, Economic Development, and Sustainable Infrastructure Committees.[2]
Igo has been outspoken in his support of the mining and timber industries in northern Minnesota, and critical of the state environmental review process.[7][8] He has argued that bans on mining will send mining jobs overseas where environmental and labor standards are lower and described himself as "pro-labor, against right-to-work."[9][10] After Russia's invasion of Ukraine, Igo wrote a letter calling on President Joe Biden to increase oil production and mining to decrease reliance on foreign imports.[11]
In 2021, Igo proposed legislation to hold a wolf hunting season.[12] Igo opposed efforts to ban lead fishing tackles due to concerns with implementation and the high cost of alternatives.[13]
