Context: Donald Trump spewing bullshit about annexing Canada and Greenland. Meanwhile, Congress has been dragging their feet for YEARS on resolving Puerto Rico's territorial status.

Citizens living in US territories do not receive equal representation in congress. For instance, PR has one "delegate" to the House (not an official voting member) and no senators. Taxation without representation.

Although, at this point I wouldn't blame PR if they changed their minds about wanting to become the 51st state.
