President Barack Obama By Pete Souza

Souza covered Obama’s arrival to the Senate in 2005 and met him for the first time on Obama's first day in the Senate when he was sworn in as a Democrat from Illinois in January 2005. He documented Obama's first year in the Senate, following him in many foreign trips including Kenya, South Africa, and Russia. In July 2008, Souza published a bestseller photos book "The Rise of Barack Obama," in which this year photographs were compiled.
In May 2009 Souza began using Flickr as an official conduit for releasing White House photos. The photos were initially posted with a Creative Commons Attribution license which required that the original photographers be credited. Flickr later created a new license which identified them as "United States Government Work" which does not carry any copyright restrictions. The photos however are posted with the following disclaimer, "This official White House photograph is being made available only for publication by news organizations and/or for personal use printing by the subject(s) of the photograph. The photograph may not be manipulated in any way and may not be used in commercial or political materials, advertisements, emails, products, promotions that in any way suggests approval or endorsement of the President, the First Family, or the White House."
