Sanders also congratulated Alexandria Ocasio-Cortez, a former organizer for Sanders’s presidential campaign, on her shocking primary victory against Rep. Joseph Crowley (D-N.Y.).

“She took on the entire local Democratic establishment in her district and won a very strong victory,” Sanders said of Ocasio-Cortez. “She demonstrated once again what progressive grassroots politics can do."

Ocasio-Cortez’s win is expected to shake up politics in New York and Washington. The 28-year-old democratic socialist and first-time candidate upset Crowley, who has not faced a primary challenger in 14 years and was viewed as a potential House Speaker.
