Today on Kilmeade and Friends (9/23/10), the Comedy Channel's Stephen Colbert has been invited to testify on Capitol Hill at an immigration hearing. Brian wonders if the joke's on the committee, American taxpayers, or both? Plus, so much for the knock that it's the party of "no." The GOP is out with its 21-page "Pledge To America." Brian talks the day's big issues with Chris Wallace, anchor of Fox News Sunday, and former Fox News White House correspondent Major Garrett, among others.
