June Sidney Award winner Jose Antonio Vargas appeared on Colbert Report last Thursday to talk about his explosive story, “My Life as an Undocumented Immigrant.”

In the runup to his appearance on Colbert, Vargas gathered over 90,000 signatures to his Define American pledge, a virtual petiton advocating for immigration reform.

Colbert, who plays a blustery right wing talkshow host on his Emmy-Award winning Comedy Central show, has a longstanding interest in immigration issues. Last September, Colbert testified in character before the House Judiciary Committe about the hardships facing America’s farmworkers, an essential workforce that comprised largely of immigrants, many of whom are undocumented.
