Executive branch

In the United States, this consists of the Office of the President (including certain cabinet members and presidential staffers), as well as myriad federal agencies[?].

Executing the laws takes the form not only of making sure that laws are followed, but making sure that the legislature's will is carried out. For example, Congress may pass a law that limits the use of ozone-depleting chemicals. However, Congress may not have the time or the expertise to spell out which chemicals count as "ozone-depleting," or how to set what the tolerable levels of the chemicals will be.

Therefore, Congress will delegate that responsibility to one or more federal agencies[?], who will execute the law by defining the chemicals, setting the levels, and then enforcing them.
