As New York Attorney General, Mr. Vacco expanded the traditional role of the Attorney General by resurrecting the long dormant criminal prosecution powers of the office. He then used the expanded purview of his office to form the nation’s first Internet Child Pornography unit targeting online predators. His distinguished career has seen him before the United States Supreme Court in the case of Vacco v.

Also in his role as Attorney General, he served as lead negotiator in the multi-state litigation against the tobacco industry and was a principal signatory to the Master Settlement Agreement (“MSA”), and directed other multi-state investigations, including an anti-trust case against Microsoft.
