ST. PAUL, Minn. (AP) — Gov. Mark Dayton is defending Minnesota’s online health insurance exchange after an accidental release of the private data of more than 2,400 insurance agents.

MNsure officials say they quickly remedied the error by an employee, and will investigate it. Dayton says Friday that mistakes and glitches are to be expected ahead of the Oct. 1 launch of the online marketplace that will deliver federal health care changes to Minnesotans.
