Former 2020 presidential candidate Castro endorses Warren for White House run

Democrat Julian Castro, who ended his presidential campaign last week, has endorsed Senator Elizabeth Warren for the White House run.

Castro tweeted on Monday that he and Warren share "a vision of America where everyone counts" and that he is proud to join her "in the fight for big, structural change."

Retweeting Castro's endorsement, Warren said Castro has been "a powerful voice for bold, progressive change" and that she is honored to have his support.

Castro had been the only Latino contender for the Democratic Party's nomination. His departure helped shrink the Democratic primary field to 14 candidates, with Warren considered one of the top-tier hopefuls.

Warren, 70, has campaigned on a series of progressive policies since she announced her presidential bid in February 2019. The former Harvard University law professor is sitting at the third place in the latest RealClearPolitics polling average, behind former U.S. Vice President Joe Biden and Senator Bernie Sanders of Vermont.
