Senator Klein has since denied she actually pointed the gun at the reporter's chest. From this story in the _East Valley Tribune:
A first-term state lawmaker denied Monday she deliberately pointed a loaded gun at a newspaper reporter during an interview at the state Senate. Sen. Lori Klein, R-Anthem, admitted in a statement she took her .380 Ruger out of its carrying case during an interview last month with Arizona Republic reporter Richard Ruelas in the lounge outside the Senate chamber. But Klein, who refused to comment, instead issued a statement saying that was done for the benefit of the photographer who wanted to see the gun and the laser sight -- and that Ruelas sat down in the path of the laser. _The Republic refused to make Ruelas available. But he told KPNX-TV which, like the Republic, is owned by Gannett, that there was a separate incident, earlier in the interview, where she pointed the gun at his chest.
