Hillary Clinton said that her policies would "put a lot of coal miners and coal companies out of business" during Sunday night's Ohio town hall on CNN.

Clinton was asked by TVOne's Roland Martin about her Democratic primary success in states that tend to vote Republican in general elections, and he wondered how she could carry such states once matched up with a Republican rather than a far-left candidate like Sen. Bernie Sanders (I., Vt.).

Clinton has struggled against Sanders in states that voted for Barack Obama in 2012, losing such contests as Michigan, New Hampshire, Colorado, Minnesota and Maine.

"I'm the only candidate which has a policy about how to bring economic opportunity using clean renewable energy as the key into coal country, because we're going to put a lot of coal miners and coal companies out of business, right, Tim? And we're going to make it clear that we don't want to forget those people," Clinton said.

"Those people labored in those mines for generations, losing their health, often losing their lives to turn on our lights and power our factories. Now we've got to move away from coal and all the other fossil fuels, but I don't want to move away from the people who did the best they could to produce the energy that we relied on."

Clinton went on to say she had put forward specific plans on how to incentivize more jobs and invest more in poorer communities.
