Fulfill the duties of the executive branch and enforce the laws set forth by the legislative branch

The executive branch of our government has adopted a policy of enforcing the laws it agrees with and selectively ignoring the ones it does not. (i.e. immigration laws). The President has a constitutional obligation to uphold the laws set forth by our legislative branch. It is high time the President executes the oath of his office and abandons the policy of convenient enforcement for political gain.
