The Census Bureau has filed this brief in State of Ohio v Raimondo, s.d., 3:21cv-64. This is the case in which Ohio is suing the Census Bureau for being late with census data that the state says it must have. The Census Bureau says it is impossible to have the data by March 31. Furthermore, it says Ohio can go ahead with redistricting even before the data is available.
The hearing is March 19.
