Well, like he promised, he vetoed the Keystone XL bill. The veto came Tuesday and was expected and was the first time in five years that the president used this power. Unfortunately for Republican Party members it doesn't appear that this veto can be override. Reportedly the veto appears to be the end of discussions on this topic. We will have to wait and see if this bill comes back into play later on.
This bill relates to government because here the president used his check and balance power to enable this bill not being passed.
I can see why President Obama vetoed this bill. America in itself is one of the prettiest nations in the world. However given the choice of whether to better the economy or protect the environment, as the President of an economic leader in the world, the economy needs to be more important.
