The highest-ranking official at U.S. Customs and Border Protection is retiring.
Deputy Commissioner David Aguilar says he will be leaving the federal law enforcement agency at the end of March. He had spent more than 30 years with the Border Patrol when he became deputy commissioner of Customs and Border Protection in 2010.
In a statement issued Friday, Homeland Security Secretary Janet Napolitano thanked Aguilar and said he has worked tirelessly to secure the border.
A former chief of the Border Patrol, Aguilar has been at the head of Customs and Border Protection since being named acting commissioner from the end of December 2011 through 2012.
Napolitano did not name a successor to lead the agency, which has a workforce of more than 60,000.
