"It's still a shame that this project cost 9 times more than it was budgeted, plus the very existence of this facility appears to be an effort to keep the public from actually going inside the Capitol building itself."
I would agree that "our" government will go to great lengths to distance themselves from "we, the people".

I disagree with that but it does seem to be a bomb shelter for Congress, inspired mainly by 9/11 and the prospect of an airliner zooming down the Mall and plummeting into the Capitol dome.
I once had a job that brought me into the Capitol several times a week, and I can understand the need to have some kind of immediate escape shelter there. The Capitol is (a) now a target for terrorists and (b) an old building with old building weaknesses and old building inconveniences of entry and exit.
It’s doubtful that anyone who makes it to the underground visitors center will not stick around to take a tour of the Capitol building itself.
