Foxx is the first African-American Cabinet nominee of Obama's second term. The initial Cabinet picks of the president's second term -- Secretary of State John Kerry, Defense Secretary Chuck Hagel and Treasury Secretay Jack Lew -- were all white men, which led to criticism of the lack of diversity in the selections.

U.S. Attorney General Eric Holder is the only African-American to lead a Cabinet agency. Earlier this month, Foxx announced he wouldn't run for re-election in the Queen City.
