Trump tweets condemnation of "all types of racism" ahead of Unite the Right rally

One day before people gather in the nation's capital for the second "Unite the Right" rally, President Trump tweeted that he condemns "all types of racism and acts of violence."

Why it matters: Trump stirred controversy following last year's rally in Charlottesville, Virginia, arguing that "both sides" were to blame for the destructive riots that resulted in a woman's death.
