Easy to brush off:
-Did business with Iranian government
I'm not so sure about that in light of the
Iran and Libya Sanctions Act of 1996;
Comprehensive Iran Sanctions, Accountability, and Divestment Act of 2010;
Executive Order 12959: Prohibiting Certain Transactions With Respect to Iran;
Executive Order 13553: Blocking Property of Certain Persons with Respect to Serious Human Rights Abuses by the Government of Iran;
Executive Order 13574: Authorizing the Implementation of Certain Sanctions Set Forth in the Iran Sanctions Act of 1996;
Executive Order 13590: Authorizing the Imposition of Certain Sanctions with Respect to the Provision of Goods, Services, Technology, or Support for Iran's Energy and Petrochemical Sectors; and probably a number of other U.S. laws.
