Do I have any legal grounds to sue a company if hired and not given the full run down of why other than we really need you.

I was hired by a company to be the Assistant Facility Security Officer. Once relocated out of state and purchasing a home. One week into the job I found out we almost failed our inspection had multiple findings. Which can result in a loosing the clearance level and if not corrected will result in termination and a lose of my personal clearance. I moved from an area to an area with my family took on all the debt. To now worry about loosing my job. 1 month in promoted to the head position to where when the ax falls it's my head. I feel like I have been set up to be the corporate scapegoat.
