Lori Lightfoot, the Democrat lesbian mayor of Chicago, took to Twitter Monday to warn others in the LGBTQ+ community that the Supreme Court would be “coming after us next,” following the leaked draft opinion striking down the key abortion precedent Roe v. Wade (1973).

“To my friends in the LGBTQ+ community—the Supreme Court is coming for us next,” Lightfoot wrote on Twitter. “This moment has to be a call to arms. We will not surrender our rights without a fight—a fight to victory!”

Lightfoot had announced an initiative to make Chicago an “island of reproductive freedom” and a “safe haven” for abortion in the Midwest earlier Monday. Her “Justice For All Pledge” dedicates $500,000 towards access to abortion in her city, including transportation and lodging for women coming in from out of state.
