According to the Center for Responsive Politics, BP is the United States' hundredth largest donor to political campaigns, having contributed more than US$5 million since 1990, 72% and 28% of which went to Republican and Democratic recipients, respectively. BP has lobbied to gain exemptions from U.S. corporate law reforms.<76> Additionally, BP paid the Podesta Group, a Washington, D.C.-based lobbying firm, $160,000 in the first half of 2007 to manage its congressional and government relations.<77>
In February 2002 BP's chief executive, Lord Browne of Madingley, renounced the practice of corporate campaign contributions, noting: "That's why we've decided, as a global policy, that from now on we will make no political contributions from corporate funds anywhere in the world."<78>
Despite this, in 2009 BP used nearly US$16 million to lobby US Congress, breaking the company's previous record (from 2008) of US$10,4 million.<79>
