COLUMBUS, Ohio (WCMH)–A Planned Parenthood clinic was vandalized in Columbus. Red paint covered part of the building and was also splashed on the front doors.

On Monday, horns were honking as protesters waved signs. Pro-life advocates have been picketing the clinic on E. Main St. in Columbus each week day for months.

Protestor Dave Daubenmire said, “We know everybody is going to point the finger at us that we’ve done it. But, we’ve been out here everyday since mid-August and we’ve had no incidents at all.”

The message of the vandals was clear. Their message said, “Satan Den of Baby Killers God See All, Mark 9:42.”

Daubenmire told NBC4 he saw the vandalism when he arrived and does not condone the tactic.

“We do not agree with that,” he said. “Whoever did that, let’s prosecute them to the fullest extent of the law.”

Planned Parenthood volunteers remained in the parking lot with a visible security presence through the day.

Planned Parenthood did release a statement saying in part, “The individuals responsible for this act hope to send a signal that using acts of violence will intimidate healthcare professionals and the women we serve. They are wrong. At Planned Parenthood, our doors will stay open… No matter what.”

Those doors did indeed remain open as the protesters continued what they call their daily vigil, pleading for lives of babies that will be aborted.

Daubenmire added, “We’re more concerned about the red blood that’s inside the building than the red paint that is on the outside of it. To us, it is just a distraction of what’s really going on inside that place.”

Planned Parenthood also said security measures will remain in place to make sure women can access the healthcare they need.

Volunteers started painting over the signs of vandalism Monday night.
