ST. PAUL, Minn. (AP) — A longtime state representative won't seek re-election amid questions about his role at a nonprofit organization.

Democratic Rep. Joe Atkins says he won't seek his seat again in 2016. Atkins has represented the Inver Grove Heights district for seven terms.

Atkins tackled big issues during his tenure, from setting up Minnesota's health insurance exchange to resisting efforts to undo the state's Sunday liquor sales ban. But he's been embroiled in questions about his leadership at a local school scholarship nonprofit.

The Star Tribune reported last week that Atkins' three children received scholarships from his organization. Atkins says he wasn't involved in those decisions.

Atkins says he may run for the Dakota County Board. He's previously suggested a bid for statewide office.
