The Justice Department is investigating whether leaders in the Black Lives Matter movement defrauded donors who contributed millions of dollars during racial justice protests in 2020. That's according to multiple people familiar with the matter. In recent weeks, federal law enforcement officials have issued subpoenas and warrants as part of an investigation into the Black-led organizations that helped spark a national reckoning on systemic racism. The investigation invites fresh scrutiny to a foundation whose leaders in recent years have faced criticism about their public accounting of donations. But the recent burst of investigative activity is also unfolding at a time when civil rights groups have raised concerns about the Trump administration targeting left-leaning groups.
