Capitol Gang

[Emsi]

I am about to translate "amidst the pomp and pageantry of Parliament Hill
lives the real capitol gang" and I wonder about the expression "capitol gang". The show is about cats living in the Parliament Hill. So, what meaning do capitol gang have?

 

[Anglika]

Without more context, it is a gang of cats living on [Parliament Hill, which is being likened to Capitol Hill]

Where is this set?
