Minnesota Governor Mark Dayton announced Tuesday he has been diagnosed with prostate cancer, a day after he passed out while delivering the State of the State address.

Aides and lawmakers rushed in to help, laying him down on the floor. Earlier, the governor looked shaky as he walked into the house chamber and at one point stumbled.
