Do I have any legal recourse? What governmental agencies enforce such issues?

During the hiring process, I disclosed a military conviction that occurred 13 years prior. Being the senior hiring manager for 2-years, it's well known that convictions not related to the nature of business, in excess of 7-years and disclosed are seldom a bearer to employment (very fair policy). Thus, after a few follow-on questions related to the conviction from HR, I was hired in compliance with company policy. The new position required I relocate so I uprooted my family of five and moved from California to Organ. My wife couldn't find gainful employment in her field to save her life, but I was performing so well, I was convinced I would be promoted and moving soon. As expected, I was promoted in less than a year and relocated to Colorado. I performed exceptionally well at this new post for almost a year. On March 14th 2018 I learned that a disgruntled employee had taken it upon herself to “investigate” all of her prior managers (which included me) to see if she could uncover embarrassing or incriminating information. Although it was believed I was not her main target, I was found to be one of opportunity. She happened upon the conviction somehow and begun disseminating the information to any person in the company she still had contact. No doubt to right some perceived slight by having a family of five be without income. Although the conviction was fully disclosed and part of my HR file, as one would expect, my immediate supervisors had no knowledge of the contents of my HR file. They knew now--- and immediately suspended me “pending further investigation”. When I was suspended, they acknowledged that I had disclosed the conviction but NOW had a problem with my personal statement I included. They gave me a copy along with a copy of the summary from the military appellate court and told me to “add more clarification”. I had no problem adding more clarification, so I asked what portions they needed clarified, but they refused to tell me. Confused, I asked for clearer instructions. They only repeated that they “need more clarification”. At this point I was convinced that they had decided to fire me regardless of whatever “clarification” I would provide. I submitted more general clarification two days later and I was terminated on the 14th of March. I was told that I was being terminated because I had become a distraction and they further claimed that my personal statement I included in my disclosure we “more opinion than fact – thus false”. I asked what parts we “false” but they provided no specifics. It was clear that the only “truth” they considered was that from the applet court. Including points included in my personal statement. The result was a family of five without employment left to figure out a way to get back to our home in California as they offered no settlement or means to relocate back to California. I have been seeking a lawyer willing to advise and perhaps even negotiate for some compensation for relocation, but most refuse to even look at the complaint until I pay upwards of $500. Although I'm not without financial means and willing to pay for representation if necessary, I'm not willing to put money to a case that may not have any legitimate recourse.
