After the Senate vote , Mayors Against Illegal Guns ran ads in 13 states either in support of Senators who voted to pass the legislation or in opposition to lawmakers who voted against it . The group spent approximately $ 12 million on these advertisements . Mayors Against Illegal Guns also ran a bus tour , similar to the bus tour it organized following the shooting of Giffords , entitled " No More Names . " The " No More Names " tour visited 25 states in 100 days to build local support for passing gun violence prevention legislation in Congress . '' No More Names '' is a program launched on June 14 , 2013 ( the six month anniversary of the Sandy Hook Elementary School shooting ) with the stated purpose to " pass common-sense laws , including comprehensive background checks , that will reduce gun violence and save lives . " The program revolves around a bus tour of twenty-five states in one hundred days starting in Newtown , Connecticut . At each stop " gun violence survivors , mayors , faith leaders , and other community members will read aloud the names of Americans killed with guns since Newtown . " This is to encourage members of Congress " to pass common sense gun laws . " MAIG organizers issued an apology after speakers mistakenly included the name of Boston marathon bombing perpetrator Tamerlan Tsarnaev among a list of shooting victims read aloud at a gun control rally in Concord , New Hampshire — an error noted in the '' New Hampshire Union Leader '' and criticized by the New Hampshire Republican Party , amongst others . Further inspection found that the list also contained the names of at least ten murder suspects including former Los Angeles Police Department officer-turned-fugitive Christopher Dorner . In response , the group issued a statement explaining that it used a list compiled by Slate.com as its source
