Nigeria is reportedly planning on filing charges against former U.S. Vice President Dick Cheney in a $180 million bribery investigation involving Halliburton, the company he headed before taking office. A Nigerian prosecutor says Cheney and executives from five foreign corporations, including Halliburton, will be indicted in the coming days and that an arrest warrant could be issued through Interpol. Halliburton has been accused of bribing Nigerian officials to win a lucrative gas project during the time Cheney was CEO.
