In early May, Politico reported, citing a leaked draft majority opinion by US Supreme Court Justice Samuel Alito, that the court had voted to overturn its decision in the Roe v. Wade case.

President Joe Biden has said that the ruling that legalizes undergoing abortions throughout the United States should not be overturned. He also suggested that US voters elect more "pro-choice" lawmakers during the midterm elections in November.
The Supreme Court ruled in the Roe v. Wade case in 1973 to extend constitutional protection of women's rights to undergo abortion without undue government restrictions. The 1992 decision in the case of Planned Parenthood v. Casey upheld the earlier ruling.
