The GOP-led House passed a bill that would eliminate noncitizens from the tally gathered during a census and used to decide how many House seats and Electoral College votes each state gets.
Obviously they are doing this to villify immigrants and discourage participation in the census, not because they actually care about who counts for the census. Citizenship requirements are intended to scare people who are citizens but often assumed to be non-citizens from participating along with the non-citizens.
