Lee Fang is a blogger at Think Progress who spends a great deal of time trying to demonize the Koch brothers. His conspiracy theories are quite fanciful, such as this effort trying to show that Wisconsin Supreme Court justice David Prosser conspired to allow more phosphorous pollution by Koch Industries. (For a critique of the post, see here.)
His latest effort attempts to implicate Koch Industries in massive oil market manipulation. It’s a fanciful and remarkably uninformed post. John Hinderaker dismantles it here. If anything, he’s too kind. I don’t expect to agree with much on Think Progress, particularly not on regulatory issues, but I would expect some minimal effort at quality control.
