Yesterday, President Obama said that he will ask his DOJ to investigate for possible collusion amongst oil companies or other shenanigans by speculators.
As Ed Lasky from American Thinker points out, he will have to start out with his own energy and transportation secretaries (since they both vociferously long for european level gasoline prices) and then move to himself since he admitted that under his "cap and trade scheme, energy prices will necessarily skyrocket"
While DOJ is at it, they might as well look in to the Administration's policies to block drilling and refining whenever and wherever possible.
Yes Mr President. There is collusion; but it is not between oil companies - it is between your Administration and environmentalist greenies!
