(CNN) - One month after sparking a controversy over his stance against abortion rights, Republican presidential candidate Herman Cain is signing a leading social conservative group's anti-abortion pledge.
Tuesday the businessman and former Godfather's Pizza CEO and radio talk show host put his name to the Susan B. Anthony List's "Pro-Life Presidential Leadership Pledge."
Programming note: GOP presidential candidates face off at 8 p.m. ET Tuesday, November 22, in the CNN Republican National Security Debate in Washington, D.C.
"This decision is consistent with the Herman Cain we have come to know," Marjorie Dannenfelser, president of SBA List, said in a statement. "He understands the wound abortion is to America and especially to the most vulnerable among us."
Cain stirred controversy last month in an interview on CNN's "Piers Morgan Tonight." He said he was against abortion rights, but when asked about rape or incest, Cain said the government shouldn't have a say on those issues and the decision should be left to the family.
Some social conservatives slammed Cain for his remarks in the following days, prompting him to be much more vocal about his "pro-life" positions during campaign stops and interviews over the weekend.
In addition to Cain, Rep. Michele Bachmann of Minnesota, former House Speaker Newt Gingrich, Rep. Ron Paul of Texas, Texas Gov. Rick Perry, and former Sen. Rick Santorum of Pennsylvania have also signed the pledge. Rep. Thad McCotter of Michigan and former Minnesota Gov. Tim Pawlenty also signed, but they have since dropped their bids for the GOP presidential nomination.
The Susan B. Anthony List says their pledge asks declared presidential candidates to commit to four key pro-life goals if elected to the presidency in 2012:
FIRST, to nominate to the U.S. federal bench judges who are committed to restraint and applying the original meaning of the Constitution, not legislating from the bench;
SECOND, to select only pro-life appointees for relevant Cabinet and Executive Branch positions, in particular the head of National Institutes of Health, the Department of Justice, and the Department of Health & Human Services;
THIRD, to advance pro-life legislation to permanently end all taxpayer funding of abortion in all domestic and international spending programs, and defund Planned Parenthood and all other contractors and recipients of federal funds with affiliates that perform or fund abortions;
FOURTH, advance and sign into law a Pain-Capable Unborn Child Protection Act to protect unborn children who are capable of feeling pain from abortion.
