Based on Donald Trump's campaign promises, his big selling point was the creation of jobs for American workers. He is likely to do this at any cost, therefore building the pipeline would be a chance for more jobs to be created. Therefore, Trump's inauguration as President could have a big influence on the decision that has already been made.
Yes, the Army Corps of Engineers will take a different position as to the North Dakota pipeline once Mr. Trump is inaugurated. Although it is encouraging to protesters that President Obama has denied the current route, it is only a matter of time before the Republicans regain the White House and do whatever the corporations want them to.
No, the Army Corps of Engineers won't take another position when Trump is in office. As engineers they need to do the right thing for the people. Even if Trump tries to convince them to change their mind, they should not give in to pressure. Their decision is correct and they need to stick with it.
The Army Corps of Engineers made their decision based on facts of the oil industry's poor record on pipeline disasters and the rights of the Native American tribe and the care of their land. They did not make the decision on politics. Therefore, when Donald Trump becomes president, the pipeline decision should not be reversed.
