Sadly, we’ve all grown used to the idea that nothing gets through the U.S. Senate these days without the support of at least 60 senators. Procedural tricks and a misuse of the filibuster rule has ground legislation to a near halt in the years since President Barack Obama took office. But when it came to a vote to ensure that disabled persons have the same rights as anyone else—including the right to avoiding pregnancy or terminating unwanted ones—even 60 votes wasn’t enough.

The Senate voted 61 to 38 to ratify the United Nations Rights of Persons with Disabilities Treaty, which stated “nations should strive to assure that the disabled enjoy the same rights and fundamental freedoms as their fellow citizens,” according to the Associated Press. The treaty was modeled after the Americans with Disabilities Act, but anti-choice activists rallied against it, claiming it “sacrifices the most vulnerable—the disabled and the unborn—all in the name of population control,” according to Bradley Mattes, president of the International Right to Life Federation.

Although anti-choice activists claimed concern that the treaty, if ratified, could expand access to abortion and somehow impede their efforts to overturn Roe v. Wade, many of those who voted against the measure, such as Utah Sen. Mike Lee, pointed to fear of losing United States “sovereignty” as their reason for opposing the treaty.
