Can an employer fire you for something that was resolved months ago?

Obviously he can fire me, but would it be justified. Lets say that i did something wrong months ago, and the problem was brought out of the open and resolved, can he still use that as a excuse to fire me months later.

In most states, a boss doesn't need an excuse to fire you. You want rights at work? Organize.

your employer can fire you for whatever they want.
