[Trump] stepped up his attacks against wind power, claiming that the structures decrease property values and that the noise they emit causes cancer.

… He offered no evidence to support the claim.

The president also said wind turbines are a “graveyard for birds.”

…He said at a rally in Michigan last month that wind power doesn’t work because the wind doesn’t always blow.

…I know a lot about wind,” he added.
