Do I meet the requirements for a wrongful termination?

I signed a contract to work as a government contractor under a specific branch of my company. After a few weeks on the job I was offered an opportunity to work under a different branch which I was told would be higher pay due to the increased responsibility and requirements for employment. Due to the fact that the contract is funded incrementally I waited until the funding for the contract was renewed before requesting a new contract in the new job. After the company received its funding I was told that the new branch that I moved to was not funded and that because someone else has signed a contract to work in my old position that I will no longer have a job as of 1 august.
