The U.S. Supreme Court on Friday agreed to decide the legality of the Trump administration's plan to put a citizenship question on the 2020 census.

The justices said they would hear arguments during the second week of the April argument session on the administration's appeal of a federal court order blocking the question from inclusion on the census questionnaire.

U.S. Solicitor General Noel Francisco had asked the justices to act quickly to hear and decide the citizenship issue because, he said, June 30 is the deadline for finalizing the census questionnaire for printing.
