Jack Lew was sworn in yesterday as the nation's 76th Treasury secretary. Vice President Joe Biden administered the oath in the Oval Office, with Lew's wife and family and President Obama looking on.
Lew previously served as White House chief of staff, and before that as director of the Office of Management and Budget, a position he also held in President Clinton’s cabinet from 1998 to 2001.
He is expected to take part in any negotiations to reverse the sequester spending cuts that take effect today. Lew also is likely to play a key role in budget talks this month to continue funding the government.
