1. Former Arkansas Gov. Mike Huckabee:

   Well, I think states have to decide, do they follow through with legislation and create a law ? The Supreme Court can't create a law, they can invalidate one, but even then the legislative body and the executive branch has to enable legislation, executives have to sign it, they have to enforce it. The courts can't do that.

2. Rachel King:

   The preliminary ruling by a federal judge in Texas is an assault on science and the FDA’s long-standing role as the authority to make decisions on the safety and efficacy of medicines. For a court to invalidate the approval of a drug that was reviewed and approved more than two decades ago is without precedent. As legal scholars have noted, the courts do not have the medical expertise to make these types of scientific determinations.
