Sen. Bernie Sanders, I-Vt., added more national support to progressive challenger Jessica Cisneros as she runs to unseat Rep. Henry Cuellar, D-Texas, a man she has described as “Trump’s favorite Democrat.”

Cisneros is one of nine endorsements that Sanders announced on Wednesday. The others included “squad” Reps. Alexandria Ocasio-Cortez, D-N.Y.; Ayanna Pressley, D-Mass.; Ilhan Omar, D-Minn., and Rashida Tlaib, D-Mich.

“This is the most important election in our lifetime and I’m proud there are so many candidates running for Congress who understand that real change comes from the bottom on up, not the top on down,” Sanders said, according to The Hill.

“They’re all strong advocates for real change, and together we will build a movement to transform this nation so that it works for all our people,” he added.
