Totally defies MY common sense

We as taxpayers are paying the Feds to investigate speaker Black. We as taxpayers are now paying $30,000 to defend speaker Black, supposedly since he isn't accused of anything. My big question is: If he isn't accused, and isn't guilty why does he need defending? Why do taxpayers pay for this?
