Republicans are coming for Roe
In their letter, the members of Congress urge the court to consider overturning both Roe and its 1992 decision in Casey v. Planned Parenthood, which upheld the basic principle of Roe but allowed for greater abortion restrictions. They argue that the Louisiana case illustrates the unworkability of the right to abortion found in Roe v. Wade
and the need for the Court to take up the issue of whether Roe and Casey should be reconsidered and, if appropriate, overruled.
Thirty-nine Republican senators signed the brief, including former presidential candidates Mitt Romney of Utah, Ted Cruz of Texas, and Marco Rubio of Florida. Of the 13 Republican senators who declined to sign the letter, eight are up for reelection in 2020, including Cory Gardner (R-Colo.), Susan Collins (R-Maine), and Martha McSally (R-Ariz.), who are all locked in close races.
