It's absurd that physicians who have a right under federal law to refrain from performing abortions are asking the government to restrict any and all access to mifepristone. These medical professionals are not being injured, so they have no standing. If SCOTUS rules otherwise, it'll be another sign of how little the extreme-right justices value the freedoms bestowed by the Constitution.
Medical professionals have standing to sue the FDA on behalf of the unborn children who won't get to live if the FDA is permitted to make mifepristone so widely available. The FDA's weakened safeguards will also put women's health at risk and put doctors in precarious positions when forced to treat mothers who take mifepristone without professional guidance.
