Democratic National Committee Deputy Chair Keith Ellison endorsed Antifa on Wednesday, tweeting a picture of himself smiling with an Antifa handbook.
Ellison posted a picture with "Antifa: The Anti-Fascist Handbook" and asserted that the book would "strike fear in the heart" of President Donald Trump.
Antifa is a far-left group that uses violence to achieve progressive political ends, including starting riots and fires at the University of California, Berkeley. While the group claims to be anti-fascist, they routinely shut down the speech of people they disagree with. Antifa clashed with far-right protesters in Charlottesville, Virginia, last year.
