From Zero Hedge:
It also explains why after Buffett’s purchase of Burlington Northern Santa Fe (BNSF) in 2009, Obama has been so staunchly against allowing the Keystone XL pipeline: because if there is anything that would allow Buffett to preserve the momentum of his soaring oil transit business, it is maintaining a veto on any competing pipelines. A veto which Obama implemented for the latest time just a few days ago.
The train in question? One of Warren Buffett’s own: a BNSF Railway freight train loaded with crude oil.
