Former Obama HUD secretary Julian Castro has launched an exploratory committee for a possible 2020 presidential bid.

Castro tweeted: “As a kid growing up on the west side of San Antonio, I never thought that I’d one day be making this announcement: I’m exploring a candidacy for President of the United States in 2020 to renew the promise of this country for all.”

Castro says he will make an announcement on January 12, 2019.
