The San Antonio Express News reported Saturday that Castro has been contacted about a cabinet post in President Barack Obama's administration, and Castro has signaled willingness to accept it. A separate source told KSAT-TV that the cabinet spot under consideration is currently filled. Both outlets reported that the FBI is beginning a background vetting process.
The 39-year-old Castro has served as mayor of San Antonio since May 2009. Back in September 2012, Obama chose Castro to deliver the keynote speech at the Democratic National Convention in Charlotte, N.C.
Castro did not mince words with his opportunity, arguing that GOP candidate Mitt Romney's policies would "dismantle" the middle class.
"What we don't accept is the idea that some folks won't even get a chance," he said. "And the thing is, Mitt Romney and the Republican party are perfectly comfortable with that America."
UPDATE (12:40 p.m. ET): The New York Times reported Saturday that Obama intends to choose Castro as his Secretary of Housing and Urban Development.
Correction: A previous version of this post incorrectly stated that the 2012 Democratic National Convention was held in Tampa, Fla.
