His testimony will relate to his experience participating in the Take Our Jobs initiative put on by the United Farm Workers union. The initiative invited people to come and try the jobs that illegal immigrants do now, like farm work, to see if they’re really taking jobs that Americans want. Since Colbert was one of only 4 people who took them up on the offer, he’ll be testifying about it.
Why he’s doing it in character isn’t entirely clear, but I suppose he’s got some fans in Congress who wouldn’t mind spicing up what would surely otherwise be a very boring subcommittee. [via]
