President-elect Donald Trump’s multifaceted plan to deal with potential conflicts of interest while in office, announced Wednesday, will not end the discussion of what he must do under the U.S. Constitution to avoid ethics problems.

Trump and Morgan, Lewis & Bockius partner Sheri Dillon, who developed the plan, stated at the Trump Tower press conference that federal statutes governing ethics explicitly exclude presidents, allowing for more creativity in dealing with ethical concerns about the billionaire president-elect.
