Halliburton was working on the Deepwater Horizon rig just before it blew up, opening the well and sending oil gushing into the Gulf of Mexico. Some experts have speculated that the company may have been to blame for the explosion. The pro-oil atmosphere (and Cheney’s continued links to Halliburton) during his vice presidency, have also come to the fore since the accident, on April 20.
In 2005 President Bush signed the Energy Policy Act, which retained the focus of Cheney’s report, into law. It included what has become known as “the Halliburton loophole” — which removed authority from the Environmental Protection Agency to regulate a potentially dangerous gas drilling process invented by Halliburton.
