The Trump administration’s decision to ask U.S. residents about citizenship status on the 2020 Census is set to go to trial Monday morning after the U.S. Supreme Court denied a request from the Trump administration to delay the proceedings.

The Supreme Court said in a one-line order Friday evening that it would not delay the trial beyond the Nov. 5 start date while it reviews a decision from U.S. District Judge Jesse Furman of the Southern District of New York in July that allowed extra-record discovery in the case.
