The Supreme Court has "burned whatever legitimacy they may still have had" with their ruling last week overturning Roe v. Wade, Massachusetts Sen. Elizabeth Warren said on Sunday.

"They just took the last of it and set a torch to it," Warren, a Democrat, told ABC "This Week" co-anchor Martha Raddatz in an exclusive interview. "I believe we need to get some confidence back in our court and that means we need more justices on the United States Supreme Court. We've done it before, we need to do it again." (Warren has previously called for expanding the number of justices, including in an op-ed in The Boston Globe in December.)

In a Friday decision, the high court overturned the landmark holding in Roe, instead ruling that there was no constitutional guarantee to abortion access. Justices voted five to four to reject Roe and six to three in favor of Mississippi's ban on abortions after 15 weeks of pregnancy, in the underlying case of Dobbs v. Jackson Women's Health Organization.a
