Sen. Kirsten Gillibrand (D-N.Y.) announced on Tuesday that if she is elected president, she will only nominate judges who vow to back Roe v. Wade, the historic 1973 ruling that legalized abortion.

“A woman’s right to make her own personal health decisions is nonnegotiable,” Gillibrand wrote in a Medium post. “So, today I’m announcing that as president, I will only nominate judges ― including Supreme Court justices ― who will commit to upholding Roe v. Wade as settled law and protect women’s reproductive rights.”

Gillibrand, who’s been an ardent supporter of women’s rights since she first became a senator in 2009, pointed to the onslaught of anti-abortion policies implemented in just the last few years.

The U.S. has enacted more than 450 state laws restricting access to abortion across the country since 2010. In 2019 alone, Ohio, Kentucky, Georgia and Mississippi have passed laws banning abortion after six weeks, a point at which many women don’t even realize they’re pregnant. The Alabama House passed legislation last week banning nearly all abortions, with no exceptions for rape and incest. And Texas lawmakers are considering the death penalty for any woman who undergoes an abortion procedure.

Gillibrand also called out President Donald Trump, writing that women deserve a president who will trust them to make the right decisions about their own bodies.

“Women deserve a president who understands the real stakes of this fight for the judiciary,” she wrote.
