Fine - they've investigated, if they already have these files. Where's the evidence of criminal activity?
I'm not willing to allow this because I'm not willing to allow the Clintons to do the exact same thing. Any power we give to this President or his administration will be retained by one we won't trust to use it wisely.
The Clintons were scrutinizing FBI files on individuals that could thwart their hidden agenda. Investigating activities of organizations that, because of their political agenda, are obviously willing to throw the baby out with the bath water is a different matter altogether. However I can understand the logic in your thinking.
