ST. PAUL, Minn. (AP) — Minnesota Gov. Mark Dayton has been released from the hospital after fainting at a weekend event.

Dayton was taken to the hospital Sunday evening. Staffers say he felt mounting pressure in his lower back before losing consciousness at an event for a state representative's campaign in the Twin Cities suburb of Woodbury. Staff suggested he was dehydrated at the time.

Deputy chief of staff Bob Hume said the governor was released Monday afternoon. Hume says Dayton will return to a normal work schedule Tuesday.

Questions about his health have followed the 69-year-old governor since he took office in 2011. He's had a series of back and hip surgeries, most recently an elective procedure in December. Dayton has vowed his health problems won't stop him from finishing his second term.
