Question: The former chairman of the 2016 Hillary Clinton presidential campaign worked on what team for Barack Obama?
Context: John David Podesta (born January 8, 1949) is a columnist and former chairman of the 2016 Hillary Clinton presidential campaign.  He previously served as chief of staff to President Bill Clinton and Counselor to President Barack Obama. Hillary 1984 is the title of the viral video that combines the footage of the 2008 presidential campaign web announcement by Hillary Clinton with the 1984 Super Bowl commercial by Apple Inc. for the launch of Macintosh.  The video shows the same blond female athlete from the 1984 Super Bowl commercial updated with an iPod.  The Big Brother image that she throws the sledgehammer at is replaced with Hillary Clinton announcing that she is running for president.  It ends with the original text replaced with, "On Jan. 14, the Democratic primary will begin.  And you'll see why 2008 won't be like 1984."  The Apple symbol is a morphed into an "O", which is followed by a logo for Barack Obama's presidential campaign website.  Barack Obama's presidential spokesman Bill Burton has said "Hillary 1984" was not created by the Obama campaign.  "It's somebody else's creation," he said.

It covers Obama’s life from his childhood, through his college years, his time as a community organizer in Chicago, Illinois, and his political career including his 2008 presidential campaign.  Marschall sums up his impressions of Obama by saying, “Seine Lebensgeschichte steht für den amerikanischen Traum.”  (“His life story stands for the American Dream.”) Shefali Razdan Duggal (born November 22, 1971) is an Indian-born American Democratic political activist in San Francisco who is a Presidential Appointee to President Barack Obama to the United States Holocaust Memorial Council, which supervises the United States Holocaust Memorial Museum, for a term expiring in January 2018.
