NEW YORK — A newly unsealed search warrant for Anthony Weiner’s electronics revealed he had turned the items over to a private investigative firm as the feds eyed his sexts with a minor. The warrant, signed Sept. 26, 2016, in Manhattan Federal Court, shows that Weiner handed his iPad, Dell computer and iPhone over to Granite Intelligence as the FBI investigated him for an array of offenses relating to text exchanges with a 15-year-old girl. Among the potential offenses listed on the warrant were transfer of obscene material to a minor and exploitation of a minor.
