I have an discrimination case and the EEOC sent me a letter saying I can sue in federal court I have witness statements and discriminating document.

I was wrongly demoted, I filed a charge with the EEOC, The persons in my charge was either fired or resign. Did not get a chance to question my witnesses or enter other critical papers that would show retaliation. I talk to the federal investigator and she just sent me a right to sue letter in federal court. I was on vacation and my supervisor put me in for no call no show as well as giving me points to keep me from bidding on other position. My case has more to it but this is short and straight to the point.
