Bloomberg plans to unveil the commercial Monday with the family of one of the victims shot on the campus on April 16, 2007, the New York Daily News reported. The ad is to be paid for by Americans United for Safe Streets, a gun control advocacy group funded by Bloomberg.
The commercial takes aim at a loophole in the Virginia law that exempts buyers who purchase guns at shows from private sellers from background checks.
The killer, Cho Seung-hui, a student at Virginia Tech, killed 32 people before taking his own life. He used weapons he purchased over the Internet or from licensed gun dealers, passing background checks in spite of a 2005 assessment that found he was mentally ill and should be hospitalized.
