Ohio Treasurer and Republican Senate candidate Josh Mandel has much to explain for an alleged incident caught on tape where he grabbed/pushed a campaign "tracker's" camera in an elevator. A tracker is a person hired by political groups to follow around a candidate with a video camera looking for embarrassing moments. It is a common practice and normally looks for something the candidate says, not something he might do.
Talking Points Memo has the full report and points out the biggest fact causing Mandel problems: he lied about what happened and the incident occurred in front of a Columbus Reporter. Oh yeah, and it's on video tape. The latter isn't as incriminating as it could be, since you don't see Mandel put his hands on the tracker or the camera, but you do hear what is going and and hear a witness confirm what just happened.
The Columbus Dispatch has a report outlining Mandel contradiction and what should just be called lies.
