This is Obama passing the buck to Trump by saying he doesn't want to deal with it since it marring his legacy. Obama knows that Trump can easily pressure the Corps of Engineers back on track for the pipeline. Actually a clever strategy by Obama to give the protesters a temporary victory, settled them down and let Trump take over. This time, the pipeline people will be better prepare.....they will be proactive in blockading the passage to that area and pipeline will be build sooner or later. Who knew that Obama and Trump, working hand and hand on stuff like this??? Devious politicians aren't they all???
