Bernie Sanders is the first 2020 candidate to pick up an endorsement from a member of Congress who is not from their home state.

Ro Khanna, D-Calif., announced Thursday that he is backing the Vermont independent to be the next president. The endorsement is not a surprising one — Khana tweeted in July of 2017 that Sanders should “absolutely run again in 2020!”

Khanna took to the Twittersphere on Thursday to reiterate that early endorsement.

“Bernie has spent his career fighting for working people and standing up to corporations and special interests,” Khanna said. “He has the grassroots energy and the vision to inspire voters across America.”

I am excited to endorse @BernieSanders for our next President of the United States.

Sanders announced Tuesday that he would try to win the Democratic nomination and challenge President Donald Trump, who Sanders called an “embarrassment to our country.”

With Sanders entering the fray, the field of possible Democratic candidates includes at least seven senators, including Amy Klobuchar of Minnesota, Elizabeth Warren of Massachusetts, Kamala Harris of California, and Cory Booker of New Jersey. Sen Kirsten Gillibrand of New York has formed an exploratory committee and Sherrod Brown of Ohio has also said he’s considering getting into the race.
