I'm sure Chairman Gowdy has need of something to do. He could simply apply the GOP Playbook (a.k.a. the Deacon Jones philosophy of meting out justice*) as they spent four years doing to Hillary.
*Some sportswriter attributed the methodology to Deacon Jones. "Don't bother following the movement of the ball. Just grab the entire backfield and peel the others away until you get at the ball carrier/holder." This was very much the Select Committee's approach. Grab up every scrap of paper you can, leak the smarmy ones, introduce the questionable ones as "evidence" and discard the rest.
@Bob the Coward. At what point does your right to know transcend sensible security and investigatory practice. There are accusations flying about. Do you wish to just ignore them? Wouldn't you prefer that a non-aligned person conduct an investigation to determine whether the POTUS is making deals to sell off suburban Mesa to a Russian kleptocrat? Most investigations, whether they result in prosecution or not, start from somewhere. We're not talking about Secret Mooslim Code on Rings. We're talking about a trusted adviser, friend and appointee having been caught, at minimum, making nice-nice with a foreign administration and possibly making them "promises" based on his insider position. Either(all) side(s) should want someone to get to the bottom of this.
