I agree with Natalie that congress has ceded power to the executive and judicial branches over the years. A recent examples of increased use of executive orders usurping congressional power was Donald Trump instituting tariffs on Chinese commerce. Despite most of the republican congress disagreeing with this executive order, Trump issued the executive order and it became law. Another example was when Donald Trump did not get his border wall, he declared a state of emergency, shut down the government and he managed to still get some of the money for the wall anyway. Congress has been giving up power to the judicial and executive branches because partisan politics has led to constant gridlock and inability to ever get a two thirds majority. Without a two thirds majority the president has veto power and then the case ends up in the judicial system.
