President Donald Trump will on Jan. 24 address a crowd of pro-life demonstrators at the annual March for Life, marking the first time a sitting president has attended the event since it was first held in 1974.
Trump confirmed he would attend 47th March for Life—themed “Life Empowers: Pro-Life is Pro-Woman”—in a surprise Twitter post on Wednesday, retweeting footage from the organization’s rally last year.
“See you on Friday...Big Crowd!” Trump wrote.
The event is the largest annual gathering in the United States of opponents of the Supreme Court’s 1973 ruling in Roe v. Wade. That ruling found that certain state laws outlawing abortion were an unconstitutional violation of a woman’s right to privacy, effectively legalizing abortion nationwide.
Trump will on Friday become the first president to attend the march in person in the event’s 47-year history. Republican presidents in the past chose to extend their support in other ways, either by meeting demonstrators or by sending messages of support.
For the 46th march last year, Trump addressed thousands of anti-abortion activists in a pre-recorded video, vowing to veto any legislation that “weakens the protection of human life.”
Hundreds of thousands of demonstrators are expected to attend this year’s event, organizers say.
Marjorie Dannenfelser, president of the group and a former chair of Trump’s pro-life coalition during his 2016 campaign, said in a statement that Trump’s attendance on Friday, “signals a watershed moment for the pro-life movement.”
The president last June demonstrated his commitment to protecting life before birth, as the Trump administration announced that it would discontinue federally-funded research that uses human fetal tissue from elective abortion conducted by government scientists.
Trump in December also received the first Dr. Bernard N. Nathanson’s “Courageous Witness for Life Award” for his efforts to defend the lives of the unborn.
Abortion rights activists have criticized news of Trump’s attendance, slamming it as a ploy to win over supporters ahead of the 2020 election.
