so what about fraud committed prior to being a federal employee?

In general, not removable to federal court. In Obama's case, barred by the statute of limitations, unless some state has a longer statute of limitations than I've ever heard of (typical SOl for felonies other than murder is 5 years).

a continuing fraud is not barred by the statute of limitations neither is one just discovered...
