No I am not OK with that. The first problem is that the amounts you are suggesting would violate federal campaign finance laws and I presume most state campaign finance laws. And, should you get elected, any quid pro quo would be unlawful and a conflict of interest.
It would also be unusual for Congress to pass a very specific statute with respect to a chemical. The EPA was created with an enabling statute that created the executive branch agency and gave power to create administrative regulations. The Executive branch is responsible for the Agency actions and the regulations that are made by the agency. If you think about it, do you believe ANY Senator or Representative has the scientific knowledge required to determine how many parts per million of sulfur in diesel fuel is dangerous for the environment or how much the flatulence of a cow disturbs the world’s CO2 production? This is all part of the separation of powers so vital to our form of government.
And, as I indicated in my earlier response and @WildRose addressed, the press would have complete control over what the public saw and would take over the electoral process.
