Wrongful Termination?

I was just terminated from my job after an investigation for sexual harrassment. The company told me that the result of the investigation was that I had not sexually harrassed anyone, but that in the course of the investigation the company found that I had asked for client info that I didn't need to do my job. I read through the code of ethics of my employer, and it states that misuse of this client info is not tolerated. It also states that employees may not give this information to another employee who does not need it to perform their job. I was fired, but the 4 other people in my branch that tool part in this violation were not. I believe the company fired me to make another employee happy. If this is the case, do I have any recourse against the company or the other employee who made these accussations? Since I was the only one terminated, but not the only one to take part in this do I have a case for discrimination? If I have a case, I will be in need of legal services and a consultation. Thanks in advance.
