Earlier in the day, Tom Mauser, whose son, Daniel, was killed with an assault weapon in the Columbine High School killings five years ago, tried to enter the convention hall where the NRA was meeting, seeking to urge Cheney to support extending the assault weapons ban.
Mauser was turned away by a security guard as several conventioneers applauded. A couple of conventioneers yelled "Get a life" and "Vote for Bush."
