The special counsel investigating former president Donald Trump threatened potential criminal charges against a Trump Organization employee suspected of lying to investigators, according to sources of ABC News. Jack Smith transmitted a letter to a staffer that indicated that he might have perjured himself in an appearance before the federal grand jury that ultimately indicted Mr Trump for allegedly mishandling classified documents, the sources said to ABC. The letter appears to signal Mr Smith’s interest in the Trump Organization’s handling of surveillance footage and efforts of the organization to avoid sharing footage with investigators.
