The White House has issued a Memorandum to heads of Departments on dealing with issues of preemption.
Document Excerpt
From our Nation’s founding, the American constitutional order has been a Federal system, ensuring a strong role for both the national Government and the States. The Federal Government’s role in promoting the general welfare and guarding individual liberties is critical, but State law and national law often operate concurrently to provide independent safeguards for the public. Throughout our history, State and local governments have frequently protected health, safety, and the environment more aggressively than has the national Government.
