Did Nebraska Sen. Ben Nelson and Warren Buffett Help Obama Kill Keystone Pipeline to Benefit Burlington Northern Railroad? | Video | TheBlaze.com Amazing how Obama killing the Keystone Pipeline just happens to make Warren Buffett and Senator Ben Nelson lots and lots of money. What's really amazing is that Buffet just so happens to be financing those "environmental" groups protesting the pipeline. So rather than put thousands of people to work and making the transport of oil cheaper, Obama's decision to not approve the Pipeline just happens to make a major wealthy supporter and the Democrat Senator helping that wealthy supporter lots and lots of money. Seriously, what are the odds?
