President Obama on Tuesday night delivered a video message to the NARAL Pro-Choice America annual dinner in which he thanked pro-abortion-rights activists for their work and marked the 40th anniversary of the Supreme Court’s Roe v. Wade decision legalizing abortion.

“We reaffirm our steadfast commitment to protecting a woman’s access to safe, affordable health care and her right to reproductive freedom, because we know that we are better off as a nation when women are treated fairly and equally in every aspect in life, whether it’s the salary you earn or the health decisions you make,” Obama said in the 90-second video to supporters gathered in a ballroom of the Hilton Hotel.
