A coalition of pro-life leaders are urging Iowans to support “anyone but Trump” in the upcoming caucus.

The female pro-life leaders of both Iowa-based and national pro-life organizations sent a letter to Iowans Tuesday to tell them that Republican presidential candidate Donald Trump is an “unacceptable” option for president due to his ambivalence about their cause and comments he has made that “impugned the dignity of women.”

Trump has recently faced scrutiny from pro-life activists for his claim that he no longer supports abortion.

During a 1999 interview on NBC’s “Meet the Press,” Trump called himself “pro-choice in every respect” and said that a President Trump would not work to implement a ban on partial-birth abortion.

Trump has since claimed that he has changed his views on abortion, but many pro-life activists find the details surrounding his conversion to be lacking, and his sincerity questionable.

At a press conference Tuesday evening, Trump declined to say whether or not he believes that the drug Plan B induces an abortion.

The message from the pro-life leaders made it clear that they do not believe Trump can be trusted on the abortion question:

As pro-life women leaders from Iowa and across the nation, we urge Republican caucus-goers and voters to support anyone but Donald Trump. On the issue of defending unborn children and protecting women from the violence of abortion, Mr. Trump cannot be trusted and there is, thankfully, an abundance of alternative candidates with proven records of pro-life leadership whom pro-life voters can support. We have come to this conclusion after having listened patiently to numerous debates and news reports, but most importantly to Donald Trump’s own words.

The women went on to note that “the next president will be responsible for as many as four nominations to the Supreme Court.”

“Mr. Trump has given us only one indication about the type of judges he would appoint, and it does not bode well for those who would like to see the court overturn Roe v. Wade,” they added. “Mr. Trump has said his sister, Judge Maryanne Trump Barry, who struck down the Partial Birth Abortion Ban in New Jersey, would be a ‘phenomenal‘ choice for the court.”

The pro-life leaders also noted that Trump has floated the name of former Sen. Scott Brown (R-Mass.), who is pro-choice, as an option for a potential running mate.

“If one truly believes, as we do, that abortion is the taking of an innocent human life and is committed to the pro-life priorities of ending abortion after five months, and defunding the nation’s largest abortion business, Planned Parenthood, it would be a disaster to have a vice president who disagrees,” they wrote.

The coalition also said that they are “disgusted” by Trump’s “treatment of individuals, women, in particular.”

“He has impugned the dignity of women, most notably Megyn Kelly, he mocked and bullied Carly Fiorina, and has through the years made disparaging public comments to and about many women,” they continued, adding that they find the idea of a president who “has profited from the exploitation of women in his Atlantic City casino hotel which boasted of the first strip club casino in the country” distasteful.

“America will only be a great nation when we have leaders of strong character who will defend both unborn children and the dignity of women,” they concluded. “We cannot trust Donald Trump to do either. Therefore, we urge our fellow citizens to support an alternative candidate.”

The coalition is comprised of Star Parker, founder and president of Urbancure; Penny Nance, president and CEO of Concerned Women for America; Beverly LaHaye, founder and chairman of Concerned Women for America; Denise Bubeck, a member of and Iowa volunteer for Concerned Women for America; Marjorie Dannenfelser, president of the Susan B. Anthony List; Marilyn Musgrave, vice president of government affairs for the Susan B. Anthony List; Jenifer Bowen, executive director of Iowa Right to Life; Kendra Burger, director of educational outreach for Iowa Right to Life; Luana Stoltenberg, an Iowa leader for Operation Outcry; and Christine Hurley, an Iowa pro-life activist.
