Completely unconstitutional and horrible! And the Republicans pushed it!
People have a right to know when Monsanto’s ‘safe,’ GM toxins are in food, but now the Fed (former Monsanto employees run the FDA) decides what is right & rules the states, unconstitutionally:

“Rep. Mike Pompeo (R-Kan.), who authored the bill, called mandatory labeling laws — which have already passed in Vermont, Connecticut and Maine — unnecessarily costly given that GMOs have been deemed safe by the Food and Drug Administration (FDA)

In many ways, the Republicans are getting worse than the Democrats!
