Republican presidential nominee Donald Trump on Friday will launch a political coalition aimed at severely limiting or ending legal abortion in the United States.
The coalition will be headed by Susan B. Anthony List President Marjorie Dannenfelser, sources tell Circa.
In May, Dannenfelser wrote an op-ed urging other anti-abortion conservatives to support Trump.
The Susan B. Anthony List group, boasting 465,000 members nationwide, is one of the largest anti-abortion groups in the nation. They work to elect candidates opposed to abortion to office.
Marjorie Dannenfelser, pictured here, will head Trump's new coalition. She has been a leader in the anti-abortion movement for more than 20 years.
Trump's history with abortion
Trump's bonafides on the abortion issue have been a point of consternation for conservatives fighting to end legal abortion. In 1999, he said on "Meet the Press" that he "is very pro-choice."
Since announcing his candidacy, however, Trump has said multiple times that he has "become pro-life."
He supports defunding Planned Parenthood and legislation that would outlaw abortions if a woman is more than five months pregnant.
Knights of Columbus-Marist poll
According to a Knights of Columbus-Marist poll done this summer, 51 percent of Americans are anti-abortion, and 78 percent support some restrictions on abortions.
(The Knights of Columbus is a Catholic-based fraternal organization. The Roman Catholic Church is opposed to birth control or abortion)
Friday's announcement comes as Trump continues efforts to unite conservatives behind his campaign. The latest Real Clear Politics poll average finds Trump less than 2 points behind Clinton nationwide.
