By the late 1990s Bracewell & Patterson was known as the largest recipient of oil-industry lobbying contracts. In March 2007 it was revealed that a lawyer at Bracewell & Giuliani was acting as a lobbyist on behalf of the Houston-based, Venezuelan state-owned petroleum company Citgo before the Texas legislature, with the firm receiving $100,000 to $200,000 in billings after having registered to lobby for Citgo on April 26, 2005, less than a month after Giuliani joined the firm. Citgo had been the focus of boycott efforts due to the Socialist policies of President Hugo Chavez and allegations by the U.S. government that Venezuela had "not cooperated" in the War on Terror. Giuliani's presidential campaign said he did no lobbying for Citgo. As of May 2007, the firm no longer lobbied on behalf of Citgo.
