Three states would likely lose seats in the House of Representatives if President Trump's order stands to exclude illegal immigrants from the apportionment process that allocates seats based on the census.
According to a study from the Pew Research Center, California, Florida and Texas would each end up with one less representative than they would otherwise get, based on overall population change.
As a result of those states losing seats, three other states would keep seats that they otherwise would have lost, the Pew Research Center said. Because California, Florida and Texas would be losing seats, the apportionment process that splits up the 435 House seats would result in Alabama, Minnesota and Ohio keeping all of their current seats instead of losing one seat each.
