Puerto Rico's streets crawl with heavily armed, masked mercenaries bearing no insignia or nametags

Imperialist history aside, can anyone cite contemporary documents indicating the current US govt wouldn’t be thrilled if PR decided to declare independence? As I understand it, the statehood issue never having traction in congress is because PR would be a new blue state with no potential red state to balance it.

This new state “balance” has been a problem since antebellum times. Most recently AK balanced HI. The only other potential new state is DC, also blue. You’d have to split a red state like TX in 2, or slice populous but regionally divided states like CA, NY or FL make a new red state. Downstate NY would LOVE to be cut free from Albany.
