No finding of wrongdoing

A bit of background and consequences of that Benghazi investigation that included Hillary's 11 hour testimony – From Terrence Heath:

Three years, ten congressional investigations, 32 congressional hearings, 204 witnesses, 11 published reports, and $20 million ($4.5 million for Gowdy’s committee alone) has yielded no findings of wrongdoing, no evidence of an intelligence failure leading up to the attacks, and no evidence of a stand down order.

Rep. Trey Gowdy from South Carolina is the chairperson of the current committee and in charge of Thursday's marathon session.

Many conservatives were annoyed with the show, calling it "a waste of time" and decrying that everything "about it is politicized."

It was such a blatant and pointless display of a political inquisition Senate Democrats sent a letter to Reince Priebus, Chair of the Republican National Committee demanding that the RNC pay that $4.5 million rather than the American taxpayer. They support their demand with several reasons: House Majority Leader Kevin McCarthy said the committee was put together to drive down Hillary's poll numbers. Gowdy and his staff focused on Clinton rather than the actual events in Benghazi. The RNC used the committee as a key point in a solicitation of money.

Of course, the RNC won't pay up. Why do so when the deep pockets of the taxpayer are so available? In addition, that would be an admission that the whole thing was politically motivated.
