I want to know the answer to the following question:
When did Carrion Jr. retire as Borough President?
All the background I'm provided with is that "Until March 1, 2009, the Borough President of the Bronx was Adolfo Carrión Jr., elected as a Democrat in 2001 and 2005 before retiring early to direct the White House Office of Urban Affairs Policy.". Is that enough to answer the question?
Answer: yes
