rebutt rebuttal. cnn's investigation could not corroborate several of the carson stories, including the description of punching a classmate in the face with his hand wrapped around a lock. >> with the investigations done and talking to the wrong people and not going to wilson junior high school where the lock incident occurred. this is stupid. i mean, if our media is no better than investigating than that, it's sick. the burden of proof is not going to be on me to corroborate everything that i ever talked about in my life. once i start down that road, every single day from now until the election, you will spend time doing that. we have much more important things to do. >> in the meantime, donald trump had a different weekend. he hosted "saturday night live" the appearance got good ratings.
