Several local sources confirm to 1200 WOAI news Saturday that San Antonio Mayor Julian Castro will be nominated by President Obama to be Secretary of Housing and Urban Development, the same cabinet position held by former Mayor Henry Cisneros under President Clinton.

Castro today had no comment on renewed speculation that he may leave the Alamo City for a top position with the Obama Administration.

"Anything on the record will have to come from the Administration," an official in the Mayor's office told 1200 WOAI news Saturday.

Castro, 39, delivered the keynote address at the 2012 Democratic National Convention and has long been seen as a 'rising star' in Democratic Party politics.  He is frequently mentioned whenever key positions in the Obama Administration come open.

Castro has also been mentioned as a possible running mate on a Hillary Clinton ticket in 2016.

Castro can point to success in San Antonio on his two highest profile initiatives.  The Pre-K for SA program is operating, and he has largely succeeded in his goal of turning San Antonio into a 'brainpower community' with a huge increase in high tech companies and jobs in the city over the past five years.

Castro is in his third term, which expires in one year.  Under the City Charter he would be able to serve one more term as mayor.

Castro also recently defended the Administration's immigration policy in a debate with Republican Lieutenant Governor canddiate Dan Patrick.
