It is precisely because of this - Document Says Oil Chiefs Met With Cheney Task Force
The document, obtained this week by The Washington Post, shows that officials from Exxon Mobil Corp., Conoco (before its merger with Phillips), Shell Oil Co. and BP America Inc. met in the White House complex with the Cheney aides who were developing a national energy policy, parts of which became law and parts of which are still being debated.
It is no surprise that Cheney would lie. That is what he does. It is like asking a dog not to bark. He has always claimed that oil companies were not involved or consulted in his energy plan. But, it also appears that Republicans gave the oil execs a chance to lie also before congress, also. When the CEO's were specifically asked bout the issue, they all said either "no" or "I don't know."
Why would Cheney lie about this? Because the law states that when non-governmental persons participate in a government task force, the notes of that task force must be made public. The intent is to stop under the table or closed door deals because we get to see what private citizens are advising the government on. But then again, transparency in government has never been a big concern to the Bush administration.
