On Monday, the Supreme Court heard a case on the Trump administration's effort to exclude undocumented immigrants from the decennial census count used to apportion congressional seats. Federal law requires the president to deliver to Congress "a statement showing the whole number of persons in each State" based on the once-a-decade census. However, President Donald Trump is pushing for an unprecedented new approach to census tabulation. "For the purpose of the reapportionment of representatives following the 2020 census ... the United States [should] exclude from the apportionment base aliens who are not in a lawful immigration status" even if they usually reside within the borders of the United States and had already been counted.
