ORLANDO, Fla. - Even though a federal judge ordered the U.S. Census Bureau to halt winding down the 2020 census for the time being, supervisors in at least one California office have been instructed to make plans for laying off census takers, according to an email obtained by The Associated Press.The email sent Wednesday from a field manager in California instructs supervisors to rate the census takers working under them with letters “A," “B," and “C." Those getting a “C" rating will be the first terminated during the next round of layoffs, according to the email which doesn't say when the cuts will take place.Census Bureau spokesman Michael Cook said no directive to make such ratings has been made from headquarters or the six regional.
