Actually CONGRESSMAN Gowdy rebutted the delay charge. If you want to read between the lines a little, here goes: Gowdy is a bit pissed over the feet dragging tactics by Hillary and State. To reply in kind, he is going to release the final report during the campaign season next year rather than as the report is finished. Do believe the ol' boy is going to rub the Lady's nose in it just a bit.
If he released the final report now, they could do a bit of cover up and when it is mentioned during the heat of the campaign, they would yell "old News already been covered". Funny how those things work when a sly fox meets a sly fox hunter.
