At a fund-raising dinner in Clear Lake, Iowa, Clinton jokes, “You may have seen that I recently launched a Snapchat account. I love it. Those messages disappear all by themselves.” (The New York Times, 8/14/2015) 

Later in the month, a New York Times article on Democratic politicians who worry about the email scandal notes, “many say, her repeated jokes and dismissive remarks on the email controversy suggest that she is not treating it seriously enough.” (The New York Times, 8/27/2015)
