Hillary Clinton lost her cool in an exchange with a Greenpeace activist:



"I am so sick, I am so sick," Clinton says, shouting and wagging her finger at the activist, "of the Sanders campaign lying about me. I'm sick of it."

Greenpeace explained the exchange, "At a Hillary Clinton rally at SUNY Purchase campus today, the presidential candidate lost her patience with a Greenpeace activist who thanked her for her commitment to climate change then asked her whether she'll reject fossil fuel money moving forward. Pointing her finger at activist Eva Resnick-Day, Clinton claimed she only takes money from people who work for fossil fuel companies and called the accusations lies."
