When it comes to the Democratic presidential frontrunner’s position on one of the most pressing issues facing humanity, author and journalist Naomi Klein isn’t mincing words: She says flat-out that she doesn't trust Hillary Clinton on addressing climate change. "I don't trust her on climate at all," Klein told Al Jazeera’s Mehdi Hasan. "As secretary of state, when she had a huge megaphone to make this an issue, to show that she understands the connections between human security and climate, she didn't use the megaphone." Condemning Clinton's "entanglement" with the corporate sector, Klein believes Sanders could win the general election.
