I don't watch American television, or any television for that matter, so I don't know for sure if there has been a televised event of such a nature. I do follow the news fairly closely, and I'm pretty sure there hasn't. Such an interview would be fantastic though. If verifiable data could be got that this was a 'leak' or it was made known that this particular segment never made it to the publics' eyes and/or ears would probably make it more sensational. All that is pure folly though, a politician would merely have to say, "It's for the kids.." or some such BS, and then regurgitate falsehoods.
High taxes is supposed to act as a deterrent to tobacco use - but all it does in reality is make government entities get in bed with tobacco companies.
More tax revenue = more government programs = more votes for politicians. They don't want that going away anytime soon, so politicians become spokesman against any dangers to that revenue.
In this case, it's working to sustain a public health crisis.
