Democratic Reps. Alexandria Ocasio-Cortez and Ilhan Omar are endorsing Bernie Sanders for president.
The Sanders campaign confirmed the backing of two members of "The Squad" on Tuesday.
The endorsements are a major boon for the 78-year-old Vermont senator, who has faced questions over his health since suffering a heart attack two weeks ago.
The 30-year-old Ocasio-Cortez and 38-year-old Omar are progressive stars and frequent targets of President Donald Trump.
Sanders' deputy communications director Sarah Ford says Ocasio-Cortez will appear with the senator at a rally in her home district in New York this weekend.
Sanders hinted at her backing during Tuesday's Democratic debate in response to a question about his age, saying his skeptics should attend his Saturday rally featuring a "surprise guest."
