ST. PAUL, Minn. (AP) - Minnesota's governor says he won't order a state investigation into Planned Parenthood as requested by abortion opponents who rallied outside his house.

Democratic Gov. Mark Dayton said Thursday the Minnesota affiliate of the women's health and abortion provider hasn't been credibly implicated in wrongdoing. Planned Parenthood has been the topics of protests nationwide following the release of secretly recorded videos of group officials discussing the sale of tissue from aborted fetuses.

Hundreds of people rallied outside of Dayton's mansion on Wednesday to ask for a probe and a cutoff of any state funds to the group where Lt. Gov. Tina Smith was once an executive.

Dayton says there have been emphatic denials by Minnesota Planned Parenthood officials of involvement in tissue transactions and says accusations lack evidentiary backing.
