Josh Mandel, a Republican candidate for the U.S. Senate in Ohio, slammed incumbent Democrat Sen. Sherrod Brown (D-OH) for falsely calling Stephen K. Bannon a “white supremacist” Sunday on CNN. Bannon is the Executive Chairman of Breitbart News and the former chief strategist in President Donald Trump’s White House, a position he assumed after serving as the CEO of President Trump’s successful general election campaign last year.
