U.S. Rep. Alexandria Ocasio-Cortez on Sunday endorsed Helen Gym for Philadelphia mayor, becoming the latest in a string of celebrities and Democrats with national profiles to back her candidacy. “Helen isn’t afraid to take on tough fights or go up against big special interests,” Ocasio-Cortez (D., N.Y.) said in a statement. “And when she does, she wins.”

In a statement, Gym said she was “honored” to receive the endorsement, saying, “From Philly to New York to Chicago, a bold grassroots movement grounded in meeting people’s basic needs is sweeping the country.”

Gym, who has before been compared to Ocasio-Cortez, has amassed a handful of endorsements from progressives across the country, including Boston Mayor Michelle Wu. She’s also been endorsed by U.S. Rep. Jamaal Bowman (D., N.Y.) and U.S. Rep. Ayanna Pressley (D., Mass.), who are Ocasio-Cortez’ fellow members of “the Squad,” a group of left-leaning lawmakers in Congress.

And she’s won the backing of a few celebrities from outside Philadelphia, including actor and longtime environmental activist Mark Ruffalo and actress Jane Fonda, whose climate-change focused political action committee contributed to Gym’s campaign.
