Trump is the 1st sitting president to address pro-life march

President Trump Friday became the first sitting president to address the pro-life March for Life, which was holding its 45th event since the creation by the U.S. Supreme Court in 1973 of the right to abortion in its Roe v. Wade decision.

He was speaking to a crowd at the Rose Garden at the White House, but his remarks were broadcast to the nearby National Mall, where an estimated 100,000 gathered to mark and mourn the advent of legalized abortion in America. Since 1973, abortion has killed an estimated 60 million unborn children.
