Vice President Mike Pence is slated to speak today at an anti-abortion rally on the National Mall in Washington, D.C., called the March for Life. His speech will mark the first time in the march’s 44-year history that a sitting vice president will address the crowd, which had gathered each year since the 1973 Roe v. Wade decision legalizing abortion. Pence is well known for his anti-abortion views. His speech comes only days after Trump’s administration reinstated the global gag order, which bans U.S. funding for any international healthcare organizations that perform abortions, advocate for the legalization of abortion or even mention the word “abortion.”
