Census Bureau says it can no longer deliver #2020Census results by the end of this year & needs Congress to change legal deadlines. "If we don't get our act together, the states are going to have some serious problems moving forward," @RepJimmyGomez says https://www.npr.org/sections/coronavirus-live-updates/2020/05/27/863290458/we-re-running-out-of-time-census-turns-to-congress-to-push-deadlines

2. "We have passed the point where we could even meet the current legislative requirement of Dec. 31” for delivering #2020Census state population counts for reapportioning congressional seats among the states, Census Bureau’s Tim Olson said during a @NCAI1944 webinar on May 26.

3. Deadlines for delivering #2020Census results, including 3/31/2021 for data used to redraw voting districts, are set by Section 141 of Title 13 of the US Code. They require an act of Congress to change. (The "census date" is 4/1/2020, aka "Census Day")

4. For now, the Census Bureau says it's planning to keep counting for the #2020Census through Oct. 31.

This uncertain census timeline spells trouble for states that have to start planning now to meet redistricting and election requirements in state constitutions and state laws.
