investigation of oil companies

I see where Edwards is proposing the investigation of the Consolidated oil companies.These companies do own every step of gasolene process so in the process the play play with prices. They have closed up refineries all over the country.If these oil companies control the prices and of course the production. Thus the Republicans can keep on lying to the American people about the shortage etc of gas.Again I propose the use of the anti trust laws. I have said it before as they sure need another TR Roosevelt to start to break up these companies. guess it istime to go to bed. Don
