The legal challenges

America First Legal, co-founded by Stephen Miller, Trump’s deputy chief of staff, is leading one of the lawsuits, filed in Florida. It contests methods the bureau has used to protect participants’ privacy and to ensure that people in group-living facilities such as dorms and nursing homes will be counted.

The lawsuit’s intent is to prevent those methods from being used in the 2030 census and to have 2020 figures revised. “This case is about stopping illegal methods that undermine equal representation and ensuring the next census complies with the Constitution,” Gene Hamilton, president of America First Legal, said in a statement.

The other lawsuit was filed in federal court in Louisiana by four Republican state attorneys general and the Federation for American Immigration Reform, which opposes illegal immigration and supports reduced legal immigration. The lawsuit seeks to exclude people who are in the United States illegally from being counted in the numbers for redrawing congressional districts.
