American presidents know that from the moment they wake up to the moment they go to bed, the lens of history is on them. For former President Barack Obama, that lens typically belonged to official White House photographer Pete Souza, who traveled just about everywhere with him. When the White House changed hands, Souza didn't stop telling Obama's story , but he started doing it in a very different way, using the photos he took on the job, to offer a silent commentary on President Trump via social media. He documents it all in his new book, "SHADE: A Tale Of Two Presidents."
