Halliburton provides construction services to the oil industry
US oil services and engineering firm Halliburton is being investigated for its accounting practices when US Vice President Dick Cheney was at the helm.
Halliburton is the latest in a string of companies to come under fire for allegedly shielding their true financial position from investors and analysts.
Mr Cheney was chairman and chief executive of the company between 1995 and 2000 and the probe revolves around the firm's accounts in 1998.
