Former Secretary of Housing and Urban Development Julián Castro is backing Sen.
Elizabeth Warren (D-Mass.). In doing so, he became the most well-known former
Democratic candidate to throw his name behind someone still in the running.
It's not a shocker — Castro, who dropped out of the Democratic presidential race last week, always spoke highly of Warren and never challenged her during the primary — but Warren received the news warmly.
Castro didn't gain much traction during his campaign, but some analysts think his endorsement could be valuable for Warren, in part because of his heavy focus on
immigration and criminal justice.
