Republican presidential candidate Donald Trump has signed a pledge from an anti-porn group "Enough Is Enough," vowing to he will fight the proliferation of erotic materials and pornography if elected.

The pledge was created by "Enough is Enough", a group that has since 1994 "pioneered and led the effort to confront online pornography, child pornography, child stalking and sexual predation with innovative initiatives and effective communications," according to its website.

The pledge, signed by the billionaire businessman last month, primarily seeks to prevent the exploitation of children online, but also calls for more aggressively enforcing "Internet obscenity laws," advancing other public policies to protect children from porgnograhy, and calls for viewing porn as a "growing public health issue" that is "deforming the sexual development of younger viewers."

The group also said that Trump has promised that he would "give serious consideration to appointing a Presidential Commission to examine the harmful public health impact of Internet pornography on youth, families and the American culture."

"I am encouraged by Mr. Trump's commitment to uphold the rule of law, which is demonstrated by his signing of the pledge," EIE president Donna Hughes told the Washington Examiner. "I am confident that if elected president, Mr. Trump will follow through on the commitments."

The WE report notes that the move could "win him some points with conservatives, who have struggled to accept a Republican presidential nominee who brought the first strip club to his casino in Atlantic City, is married to a woman who once posed nude for GQ and has said a host of derogatory things about females."

However, Trump's decision to sign the pledge has confused some, as the GOP nominee himself appeared on the cover of Playboy magazine back in 1990.

In addition, The New York Post earlier this week published two large photospreads of Trump's wife Melania completely nude. The explicit photos are reportedly from shoots in the mid-'90s when she worked as a model under the name "Melania K".

When asked about the photos, Trump dismissed the idea that such images are pornographic, stating, "Melania was one of the most successful models, and she did many photo shoots, including for covers and major magazines. This was a picture taken for a European magazine prior to my knowing Melania. In Europe, pictures like this are very fashionable and common."

Meanwhile, Concerned Women for America President Penny Nance, whose group pushed for the anti-porn language, noted her group doesn't endorse presidential candidates but told the WE she's "confident Donald Trump will listen to the concerns of conservative women and parents on this issue."

She added that Trump's choice of Indiana Gov. Mike Pence as a running mate has given groups like CWA more assurance Trump will follow through on his promise to fight issues like pornography.

"When you look at the man he has chosen as vice-president ... you can see that, for all the glamour and celebrity he is known for, Trump seems to be committed to a brand of governing that will consider policy issues seriously," she said. "And nothing is more serious than the sexual exploitation of women and children."
