President Donald Trump has instructed the Commerce Department to have the Census Bureau start work on a new census that would exclude immigrants who are in the United States illegally from the head count which determines political power and federal spending.

The Census Bureau already was facing a shortened schedule of two and a half months for processing the data collected during the 2020 census — about half the time originally planned. The Census Bureau would not say Thursday what the anomalies were or publicly state if there would be a new deadline for the apportionment numbers. “These types of processing anomalies have occurred in past censuses," Census Bureau director Steven Dillingham said in a statement. “I am directing the Census Bureau to utilize all resources available to resolve this as expeditiously as possible. “The notion that the 2020 Census data could be processed in half the time scheduled given all the obstacles & challenges that Census Bureau encountered defies logic."
