I believe you need to file a complaint with the Equal Employment Opportunity Commission (EEOC) HERE. Also, the firing had to be based on a true reason for termination, not a political play. You can also file a Civil Claim of Personal Injury against them for the cruel treatment, harassment, and humiliation they caused you. Depending on the size of the company and if they are under a Corporation, you may also be able to file a claim against the company for wrongful termination, harassment, and violating your civil rights.

I highly recommend getting an attorney to represent you in the matter either Personal Injury, Employment Law, or both.
If you need further assistance, please contact me with additional information or questions. Good luck & God bless!
