Mayors Against Illegal Guns today announced a new television ad holding Senator Jeff Flake accountable for not keeping his word to Arizonans Caren and Tom Teves, whose son Alex was killed in the Aurora theatre shooting while shielding his fiancée. The Teves, who voted for Senator Flake in 2012, sent a letter to their Senator asking him to vote for background check legislation and he responded that, "strengthening background checks is something we agree on." Just one month later, Senator Flake voted against bipartisan legislation proposed by NRA A-rated Senators Pat Toomey and Joe Manchin -- and supported by Senator John McCain -- that would have closed loopholes that make it easy for dangerous people to get guns.
