By “do their job” you mean just agree with everything the president wants, correct? Shouldn’t the president also do his job and work with Congress, or is he an all-knowing Sith lord who can never be wrong? They were “elected” by their constituents to do many jobs, not just hand everything over to Dear Leader.

The president’s job is to enforce EXISTING laws.

“It’s a shame that Congress cannot do their job, and executive action is more and more necessary to make anything happen.”
