Freshman Missouri Rep. Cori Bush tweeted a photo of the high-profile group of progressive Democratic lawmakers, joined by their latest members. “Squad up,” Bush captioned the shot, which saw her and fellow freshman Rep. Jamaal Bowman of New York join the four founding members, Reps. Alexandria Ocasio-Cortez (NY), Rashida Tlaib (Mich.), Ilhan Omar (Minn.) and Ayanna Pressley (Mass.).
