Washington, DC (LifeNews.com) -- A collection of pro-life groups has launched a national campaign to de-fund the Planned Parenthood abortion business responsible for more than 25 percent of all abortions in the U.S. On Thursday, leaders from 20 pro-life groups will come together to draft a joint resolution.

That plan will outline the details of how they hope to cut off federal and state government funding to the abortion business.

The pro-life advocates will gather at the "Planned Parenthood: BAD for America" summit, organized by the Pro-Life Action League, to share techniques that have proved successful in impeding Planned Parenthood's objectives across the country.

This is the first time so many pro-life groups from across the country have gathered in a single location to address fighting Planned Parenthood, whose political action committee has endorsed Barack Obama for president.

"Each pro-life group emphasizes different strategies for effectively reducing abortion, but we all share a common goal - to stop abortion forever," Eric Scheidler, of the host group, told LifeNews.com.

"Even as the abortion rate declines nationally, Planned Parenthood's abortion numbers are on the rise - and now Planned Parenthood has launched a major expansion, aggressively targeting the young and vulnerable of our nation," he explained. "Today more than ever, the pro-life movement must stand together to oppose Planned Parenthood."

Scheidler led the effort last year to oppose the opening of a massive new Planned Parenthood facility in Aurora, Illinois and he has advised other pro-life groups around the country on mobilizing grassroots resistance to Planned Parenthood's designs on their communities.

The summit agenda includes presentations by experts who are veterans from the pro-life battlefield, including Tom Brejcha, chief counsel of Thomas More Society/Pro-Life Law Center.

Kristan Hawkins, executive director of Students for Life of America, which has exposed Planned Parenthood's willingness to accept racially motivated donations through a series of widely viewed YouTube videos, will also be involved.

Jim Sedlak, executive director of STOPP Planned Parenthood, a watchdog group, will also participate.

"Planned Parenthood is a huge organization, flush with cash, but no enemy is too big when we work together," Scheidler says. "When all of these pro-life groups gather on Thursday, America will see a unified front in the battle to save unborn babies from their number-one enemy, Planned Parenthood."
