Wallace Unplugged: Friday Pre-Show Edition

"Fox News Sunday" anchor Chris Wallace previews this week’s show, including an exclusive interview with Republican Presidential Candidate Tim Pawlenty, who made waves this week with a much-hyped speech on economic policy. He’ll also discuss the latest shockwaves in the GOP presidential race– former House Speaker Newt Gingrich loses his entire senior staff, and Texas Governor Rick Perry could step into the ring.
