ST. PAUL (AP) - MNsure's chief executive is resigning from the health insurance exchange, The Associated Press has learned.

Scott Leitz will announce his resignation to MNsure's board of directors Monday, according to two people with knowledge of his decision. They said Leitz was joining a health care think tank.

The people spoke on condition of anonymity because they weren't authorized to speak before a special board meeting Monday afternoon. The purpose of the meeting was listed as "MNsure CEO update."

Leitz didn't immediately respond to an email. A MNsure spokeswoman did not immediately return a call and email.

Leitz took over in 2013 after MNsure's first executive director resigned amid a troubled rollout. His departure means the exchange will have its third leader in less than two years as lawmakers debate its future.
