Issue between Two Branches of Government- Trumps Border Wall

1) research and describe an issue in the US that
illustrates how at least two of the branches (or levels) of government interact with one another
(cooperation, conflict, or both). It is also possible to include intra-branch conflicts, if there is an interbranch element, too. The issue can be social, political or economic, or some combination of those
aspects. Topics may occur to you simply through paying attention to US politics on a daily basis.
• and (2) provide an analysis of the functioning of US government by examining how the issue has played out thus far.
