Bush, a Democratic Missouri congresswoman and defund-the-police activist, on Monday said, “When we marched in Ferguson, white supremacists would hide behind a hill near where Michael Brown Jr. was murdered and shoot at us,” adding the alleged shooters “never faced consequences.” According to Ferguson police chief Frank McCall, however, there is no record of such an incident.

“Not that I’m aware of,” McCall, the city’s fourth black police chief, told the St. Louis Post-Dispatch. Bush, who did not return a request for comment, defended her claim, with her campaign telling the Post-Dispatch, “While on the frontlines of the Ferguson Uprising, Congresswoman Bush and other activists were shot at by white supremacist vigilantes.”

There is at least one shooting that occurred in the wake of Brown’s death that matches Bush’s description of coming from “behind a hill” in Ferguson. But in that instance, two police officers were shot outside the Ferguson police headquarters—nearby protesters said the shots came from “a hill behind a dwindling group of demonstrators” who were “gathered across from the police department.”
