Democratic presidential candidate Bernie Sanders on Saturday mocked the president's unsubstantiated claims that wind turbines cause cancer -- an issue near and dear to Iowans, as the state leads the country in wind energy.

The Vermont senator spoke at Iowa State University, where he criticized President Donald Trump for constantly denying climate change, even though the U.S. government issued a detailed report last year saying that "climate-related threats to Americans' physical, social and economic well-being are rising."


Sanders, in a sarcastic manner, said, "(Trump) is a profound scientist, somebody who's researched the issue for years and uniquely came up with (the) conclusion" that noise from wind turbines causes cancer.

There is no scientific evidence, however, linking wind farms to cancer.

Iowa is a national leader in wind energy, with more than 4,000 turbines, which are a part of a $16 billion renewable energy investment in the state.

The 76-year-old self-described democratic socialist also said that "cowardly" Republican governors were conducting a massive effort to suppress the vote in general elections, suggesting that if they were not willing to participate in free and fair elections, they should leave politics.
