Gov. Mark Dayton to undergo third back surgery

Gov. Mark Dayton will undergo back surgery Friday morning at Mayo Clinic in Rochester, another in a series of health complications the second-term governor has endured in recent years.

Dayton's office released a statement saying the surgery is similar to procedures Dayton had in 2012 and 2015, which fused vertebrae in his lower back.
