The U.S. House of Representatives will vote Wednesday on whether to permanently ban federal funding of abortion.
GOP lawmakers like Rep. Chris Smith and House Speaker John Boehner say the extra initiative is needed to stop the Obama administration and Senate Democrats from allowing taxpayer-funded abortions.
"A ban on taxpayer funding of abortions is the will of the people, and it ought to be the will of the land," Boehner said.
"The Guttmacher Institute -- which is no friend to the right to life movement -- the former research arm of Planned Parenthood, has said very clearly and plainly that when there's no public subsidy for abortions, the number of abortions drop by about 25 percent," Smith added. "If we want fewer abortions, take away the federal subsidy."
The Family Research Council launched radio ads in 12 congressional districts urging lawmakers to support the No Taxpayer Funding for Abortion Act.
The House Judiciary Committed approved the legislation in March, which then sent the bill out for a full House vote.
