On 30th of November the Supreme Court will argue whether President Trump can exclude illegal aliens from 2020 census or not. It's interesting to note SC itself asked to postpone it until 30th of November(this was done 16th of October) 10 days later Justice Barrett was confirmed, thus she will have a chance to weight in on this. If illegals are excluded, it means California will lose many seats in Congress, many electoral votes, federal funds and the list goes on and on.
