Mr. President,
Please do not go through with this current European Union Trade deal. Your current proposal for a trade deal with the European Union would be highly devastating to the world as we know it. Giving corporations the ability to sue governments over policies and laws because it hinders their profits would put vast reforms and progress that has been made over generations of effort. Things like pollution control (do note your supposed stance against and improving the Global Warming crisis), Child Labor Laws, anti-Monopoly laws, fair trade laws, etc would all become threatened by giving corporations the power equal to that of a sovereign nation.
It's best for everyone that you give corporations no further power than they already have (which is too much now). Please consider this.
