IANAL. I would think fraud needs investigation much deeper than; "This $200 million is being spent on <insert program> that we don't need at the moment."

First you find where the money is being spent and if it doesn't match the goals of the administration, you turn it off. If there is potential for fraud, you mark the case for further evaluation and investigation. The most important first step is always to stop the bleeding and in this case, bleeding money.

You can come back to investigate at a later time. Prosecuting fraud before the bleeding has stopped is a waste of time imo.
