Washington (CNN) House Republican leaders canceled a vote on Tuesday on legislation that would have created a commemorative coin to raise money for breast cancer awareness, after some House conservatives raised concerns the coin sale funds would be used to support an abortion rights group at the center of a controversial new video.

The bipartisan bill directed the Treasury Department to mint a new coin and send some of the proceeds from it to the Susan G. Komen for the Cure and the Breast Cancer Research Foundation. But shortly before the vote on what many considered a non-controversial coin, several anti-abortion rights advocacy groups launched an effort to defeat the measure. They argued the Komen Foundation supports programs run by the Planned Parenthood Federation of America, a group that provides women's health care, including abortion services.

Backlash to a video -- circulated on Tuesday by an undercover group opposed to abortion rights -- only ignited controversy on what is already a flashpoint over a social issue. The video shows a Planned Parenthood staffer seeming to discuss the sale of body parts from abortions.

"Komen has had a close connection with Planned Parenthood for a number of years and some folks hadn't realized that," Kansas GOP Rep. Tim Huelskamp told CNN. He said several outside groups increased opposition to the bill by saying they planned to "score" the vote -- a practice of keeping tabs on each member's record on abortion-related legislation.
