President Obama will announce the latest shuffle of his Cabinet on Friday, moving his Housing and Urban Development chief to the budget office and replacing him with the mayor of San Antonio.

Mayor Julian Castro is a rising star in the Democratic Party and is among the most prominent young Latino politicians in the country. Castro delivered a keynote speech at the Democratic National Convention in 2012, the same year his twin brother, Joaquin, was elected to Congress.

If confirmed by the Senate, Castro will replace Shaun Donovan, Obama's housing chief since 2009. A White House official who confirmed the personnel moves described Donovan as a "trusted advisor" to the president who uses "data to make good decisions and drive results."

Donovan will replace Office of Management and Budget Director Sylvia Mathews Burwell, who is moving to replace outgoing Health and Human Services Secretary Kathleen Sebelius.

Castro, 39, will leave during his third term as mayor for the high-profile post. The official described him as "a leader among mayors" on housing and economic development. Castro and Donovan will join the president at the White House on Friday for the announcement.
