Barack Obama speaks at his 43rd birthday celebration and fundraiser August 4, 2004 in Matteson, Illinois. Obama is the Democratic candidate from Illinois running for the U.S. Senate and currently represents Illinois' 13th Senate District on Chicago' s South Side.
In this President's Day, we look at the life of the current commander in chief: Barack Obama.
Shortly before he was re-elected, writer David Maraniss published an extensive biography of the 44th president.
The book "Barack Obama: The Story" chronicles President Obama's childhood through his post-college years in New York and Chicago. When we spoke with David Maraniss last fall, he explained why he focused on these early chapters of the president's life, long before the White House.
