This is an interesting legal issue. We held big tobacco liable when it was proven they not only hid the effects of tobacco usage, but actively lobbied against any kind of regulation that would help protect consumers, even if it was a warning on the package of smokes. I think that it's an interesting legal theory, and not so sure the gun industry can stand up to it based on past case law. Essentially then, if a lawyer can prove that XYZ gun manaufacturer was directly involved in suppression of evidence about what causes gun violence, or spent significant money to lobby congress to not even look at ways to reduce gun violence, then there may actually be cause to sue them as a matter of public health.
@Moonraker33's pithy comment is funny, but not applicable to the situaton the Secratary is looking at. Plus, it would still need to be litigated all the way to the Supreme Court, and even with a conservative court, the precedent stands, no?
As for the president & Coal - it's easy to get wrapped around the axle of the clean power plan (it's been stayed so not in play at the moment), but the global market for coal is tanking due to other nations moving away from fossil fuels and towards renewables. China was our biggest customer for coal and they've reduced demand significantly over the last year or so. Beyond those economic factors, you have a glut of natural gas which is driving down the cost of coal, and is being used as a bridge to transition away from coal because it's cheaper, cleaner and easier to convert a station to gas as opposed to upgrading coal facilities to meet those evil emission standards for clean air.
Pretty big difference here.
Using tobacco the way it is intended to be used is deadly. A firearm isn't.
If target shooting, elk hunting, or having an inanimate piece of steel occupying space in a safe was -in itself- a detriment to the owner's health, and the firearm manufactuere tried to hide that, then we would be talking apples to apples, but it isn't and we aren't.
Remington was held responsible for the model 700 mishaps, as they should have been. It was a manufacturers defect that was killing people. No different than if a safety feature on an automobile malfunctioned and hurt/killed someone. My mom's cousin successfully sued Ford when her car combusted in her garage and burned down her home a few years ago. (Ford later recalled that model) That is entirely different than if she would have used her vehicle with malicious intent, hurt someone, and that person then sued Ford.
