Attorneys for former New York City Mayor Rudolph Giuliani on Monday asked a Manhattan federal judge to weigh “the constitutionality and legality of the government’s conduct to this point in the investigation” before any review of the material seized from Giuliani’s home and office during an early morning raid in April.

The U.S. Attorney’s Office for the Southern District of New York has asked U.S. District Judge J. Paul Oetken to appoint a special master to review which materials may be covered by attorney-client privilege, but Giuliani’s attorneys Robert Costello and Arthur Aidala said legal questions about the raid and a November 2019 “covert search and review” of Giuliani’s iCloud account must be resolved first.
