You are correct:
Who signed off on the deal?
What was the purpose of renting this specific building?
When was this deal signed and/or put into effect?
Where else did the Census Bureau first look?
Why is this information just now coming to light?
How would the Census Bureau think this was beneficial?
DId they make this deal AFTER the shooting?? Dhimmitude?
Was there competition? This is a key question as there is lots of office space up for grabs in this economy. If it’s sole source there had better be a damned good WRITTEN justification for it.
