WASHINGTON (AP) — Former Housing Secretary Julián Castro is announcing he needs to raise $800,000 in the next 10 days or he'll drop out of the presidential race.
Castro made the announcement Monday in a fundraising email, saying his campaign is in "dire need" of resources. Castro says without the money he won't be able to make the November debate and his campaign "will have to shut down."
