LAS VEGAS (AP) — Nevada conservatives are joining an effort to defund Planned Parenthood after the release of covert videos of agency officials.

Republican Assemblyman Erv Nelson is scheduled to join conservative talk radio host Heidi Harris and Republican activist Amy Tarkanian in a noontime rally Tuesday near the Grant Sawyer Building in Las Vegas.

Similar rallies are scheduled at noon local time in about 70 cities across the country. The efforts are being spearheaded by the nonprofit anti-abortion group Students for Life.

Organizers say they'd like Nevada elected officials to join the call for investigating Planned Parenthood after the release of videos showing agency officials discussing how they provide aborted fetal organs for research.

Numerous Republican presidential candidates have called for eliminating Planned Parenthood's federal funding, and three congressional committees are making inquiries.
