Jon Ward at The Daily Caller reports:

Comedy Central host Stephen Colbert is slated to testify at a congressional hearing Friday on immigration titled “Protecting America’s Harvest,” two sources have told The Daily Caller.

One Republican source said Colbert will be testifying “in character,” the Bill O’Reilly-like muse Colbert uses for his show.

A Judiciary Committee spokeswoman, confirming Colbert would testify, said the hearing matter was a “serious issue . . . this is not a TV stunt.”

Some Republicans have already expressed unhappiness with Colbert witnessing at the hearing, thinking it would make light of a serious issue.

Not a TV stunt? I hope that’s the case. After all, it’s not like they Democrats would do something as fundamentally unserious as use a totally incongruous celebrity to promote an important legislative issue. They haven’t had Lady Gaga at a political rally in, what, two days?
