The Wall Street Journal reported in 2001 that a subsidiary of Halliburton Energy Services called Halliburton Products and Services Ltd. (HPS) opened an office in Tehran. The company, HPS, operated on the ninth floor of a new north Tehran tower block. Although HPS was incorporated in the Cayman Islands in 1975 and is "non-American", it shares both the logo and name of Halliburton Energy Services and, according to Dow Jones Newswires, offers services from Halliburton units worldwide through its Tehran office. Such behavior, undertaken while Cheney was CEO of Halliburton, may have violated the Trading with the Enemy Act. A Halliburton spokesman, responding to inquiries from Dow Jones, said "This is not breaking any laws. This is a foreign subsidiary and no U.S. person is involved in this. No U.S. person is facilitating any transaction. We are not performing directly in that country." Later David Lesar would book his own flights to the Tehran office through the UK arm of KBR. No legal action has been taken against the company or its officials
