Hey, Colbert's done some genuinely brilliant work in the new Newsweek, check it for yourself.
Also, please note his support for the Iraq & Afghanistan Veterans of America, which is the group helping recent veterans treated right. IAVA supporters and Colbert are depicted right inside the magazine.
Just found, a podcast from Newsweek discussing the issue, and it includes an interview with Paul Rieckhoff, IAVA director, and a much scarier human than me. Highly recommended.
disclaimer: I'm on the board of IAVA, figuring that the vets committed to me, so I should return the favor.
