Former New York City Mayor Michael Bloomberg pointed the finger at his presidential opponent Sen. Bernie Sanders after his campaign offices were vandalized.

In the latest vandalism attack, a perpetrator spray-painted the front doors of his Knoxville, Tennessee, office either Thursday night or early Friday morning with expletives and posters that said “authoritarian,” “classist,” and “oligarch,” according to WVLT. The posters also featured derogatory comments Bloomberg allegedly made toward women and people of color that were labeled “fascist,” “sexist,” and “racist.”
