"President Trump became the first sitting U.S. president to directly address the March for Life anti-abortion rally in Washington. He spoke live via satellite from the White House Rose Garden" to the crowd on the National Mall, per USA Today:
"Previous presidents [including] Ronald Reagan and George W. Bush addressed the march via phone call or recorded message."
"[T]he annual rally ... marks the 45th anniversary Monday of the Supreme Court's Roe. v. Wade decision."
Why it matters: "Trump's speech to marchers gave the protest added visibility, rededicating himself to a conservative base that he sees as the key to his election victory in 2016."
Happening this weekend ... "Women will march again with aim to become a political force," per AP:

"Hundreds of gatherings are planned Saturday and Sunday across the U.S. and in places such as Beijing, Buenos Aires, Argentina, and Nairobi, Kenya."
