Rep. Alexandria Ocasio-Cortez sent a letter to her constituents Friday explaining why she wept during a House vote this week on a stand-alone provision to fund Israel’s Iron Dome missile defense system.

The House voted overwhelmingly on Thursday to approve the Iron Dome provision after Democratic leadership was forced to pull it from a broader spending bill because lawmakers from the party’s progressive wing objected, including Ocasio-Cortez’s fellow members of “the Squad”: Reps. Rashida Tlaib, Ilhan Omar, and Ayanna Pressley. Tlaib accused Israel of human rights abuses and war crimes during Thursday’s debate on the House floor.
