ST. PAUL — Hundreds of abortion opponents have rallied outside the home of Minnesota Gov. Mark Dayton, calling for the state to investigate Planned Parenthood.

The rally Wednesday follows the release of secretly recorded videos of group officials discussing the sale of tissue from aborted fetuses. Planned Parenthood says there is no evidence of wrongdoing.

Protesters in Minnesota want the state to start an investigation and to remove any state funds that might go to Planned Parenthood’s health-care services.

But a Planned Parenthood spokeswoman told KSTP.com that Planned Parenthood Minnesota, North Dakota, South Dakota doesn’t have a fetal tissue donation program, so there is nothing to investigate.

But organizers of the protest question that assertion. Protesters say the state should defund Planned Parenthood and find other ways to deliver women’s healthcare.
