UPDATE: CNN host Newt Gingrich appeared during State of the Union's third block to discuss an op-ed in which he compared Mandela to American Revolutionary heroes, and the subsequent backlash Gingrich received for the comments.
When reached for comment, a CNN spokesperson told BuzzFeed the following:
"The Sunday program information distributed for coverage planning generally only has room for the guest plans. Each week though, our Sunday broadcasts include field or studio segments, without guests, covering topics that may not be indicated on these listings."
