Wednesday's announcement was made in a statement by Speaker Carl E. Heastie and Judiciary Committee Chair Charles D. Lavine.
The statement said the international law firm, which has offices in Washington, D.C., and overseas, is "authorized to vigorously pursue all the evidence to determine the extent to which violations of the law have occurred."
Cuomo on Wednesday declined to comment on what he referred to as the Assembly's "review."
"I am not going to take any questions or have any comments on the review," he said in a conference call with reporters. "Let the lawyers do their job and conduct the review and then we can talk about it when we have facts established. … But other than that, I’m going to respect the review and I won’t comment on it or related matters."
