Yes, but that's nothing compared to his endorsing the revolutionary communist images of propagandist Shepard Fairey. His images glorify such mass-murdering (communist) monsters as Mao and Stalin. And Obama wrote specifically:
"Dear Shepard, I would like to thank you for using your talent in support of my campaign. The political messages involved in your work have encouraged Americans to believe they can help change the status quo. Your images have a profound effect on people, whether seen in a gallery or on a stop sign. I am privileged to be a part of your artwork and proud to have your support. I wish you continued success and creativity.
Sincerely, Barack Obama.'"
