Well, _geezer, wasn't Congressman Roscoe Bartlett the guy who Schulz & org. originally petitioned.
Actually Bartlett was only approached to arrange an meeting in Washington. He was not questioned, nor did Schulz ever mention that he would be.
The only targets for questioning, as mention by Shulz & Co., were the IRS & DOJ.
What was arranged, was not a congressional hearing at all, but a meeting arranged for constituents to meet with members of government for a briefing on taxes.
This whole thing has been hyped from the beginning by Schulz if you look over the various communications and articles that have shown up here on FR.
