In a video released on social media Wednesday morning, Julián Castro, former mayor of San Antonio and secretary of Housing and Urban Development under President Obama, announced an exploratory committee for the 2020 presidential election.

In the video, Castro described his family history coming to the United States, his mother’s service in the city council, and his brother and his political success as evidence that he “knows the promise of America.”

Castro’s twin brother Joaquín is a former state representative and current congressman who has served in House Democrat leadership since 2015.

He also goes through a litany of leftist talking points including support for amnesty, more government involvement in healthcare and education, and far-left environmental policy.

Castro, who was notorious for his tax and spend policies as San Antonio mayor, is one of the first candidates to publicly announce their run for 2020 in an attempt to unseat President Trump, whose 2020 campaign has been quietly operating since early in his presidency.
