Roger Stone, a longtime adviser to President Donald Trump, has repeatedly lied or contradicted himself on numerous issues related to special counsel Robert Mueller’s Russia investigation. Stone is a vicious racist, misogynist, liar, and conspiracy theorist who describes himself as “a 40-year friend and advisor of Donald Trump.” He worked as a paid consultant to Trump’s campaign for part of 2015 and has since advised him in an unofficial capacity. He was banned from CNN, MSNBC, and even Fox News in 2016 because of his vitriolic rhetoric.
