A photo book of Obama's career.
The Swamp: Former Chicago Tribune photographer Pete Souza began to chronicle the life of Barack Obama during the senator's first days in political office, when the Secret Service wasn't around yet.
He then joined Obama on trips to seven countries where he captured poignant moments of his life and career. He was there when Obama visited Nelson Mandela's prison cell in South Africa and when throngs of people welcomed Obama to the birthplace of his father, Kenya.
Souza has now gathered the photographs, taken with unprecedented access, into a new book, The Rise of Barack Obama. The book goes on sale this week.
"The book is basically a visual documentation of the rise of his national career," Souza said.
