Anderson Cooper 360º: Special counsel continues to schedule witness interviews even as potential Trump indictment looms

Investigators with special counsel Jack Smith’s team are expected to talk to additional witnesses over the next several weeks in their election interference probe as a potential third indictment for the former President Trump looms. One of those witnesses is expected to be a former attorney for Trump. The former president was told by the special counsel that he is a target in the investigation into efforts to overturn the 2020 election. CNN Chief Correspondent Kaitlan Collins tells Anderson Cooper who testified today and why they are an important witness. Plus, a source tells CNN that authorities in the Gilgo Beach serial killings case are working with the theory that the suspect, 59-year-old Rex Heuermann, murdered the victims inside his Long Island home. John Miller is the former NYPD Deputy Commissioner of Intelligence and Counterterrorism. He joins AC360 to discuss the investigation and the continued search for evidence.
