Obama memo kills FDA pre-emption over states

The US Food and Drug Administration, without being named directly in a presidential memorandum, has been ordered to cease its attempts to  secure pre-emptive regulatory authority over the 50 states on safety  labeling, including for pharmaceuticals. In addition, the document  calls for "heads of departments and agencies [to] review regulations  issued within the past 10 years that contain statements in regulatory  preambles or codified provisions intended by the department or agency  to pre-empt state law, in order to decide whether such statements or  provisions are justified under applicable legal principles governing  pre-emption."
