The Daily Signal first reported in September that the House Oversight and Accountability Committee opened an investigation into the potential politicization of the population count and miscounts in 14 states.

The December Oversight hearing will review the Census Bureau’s 2020 Post-Enumeration Survey, or PES. The hearing will also look at the bureau’s preparations for the 2030 Census.

“The Census Bureau’s review of the 2020 Census revealed substantial miscounts and discrepancies tending to benefit Democrat-run states,” House Oversight Chairman James Comer, R-Ky., said in a statement to The Daily Signal. “Congress has a responsibility to conduct oversight of these massive errors to ensure they are not repeated in the 2030 census.”

U.S. Census Bureau Director Robert Santos, an appointee of President Joe Biden, is set to testify at the hearing.

“Additionally, current integrity issues with the Census must be addressed,” Comer said.

He continued:

The Biden-Harris administration facilitated the worst border crisis in American history, allowing millions of illegal aliens to enter and reside in our country unlawfully. To ensure only U.S. citizens are counted for the apportionment of congressional seats and Electoral College votes, Congress must pass the Equal Representation Act to add a straightforward citizenship question to the Census. We look forward to hearing Director Santos’ testimony and ensuring the Census Bureau takes the necessary steps to deliver a fair and accurate 2030 census.

The 2020 Post-Enumeration Survey found statistically significant miscounts in the 2020 Census in 14 states.

The Biden administration’s Census Bureau revealed in May 2022 that it undercounted the Republican-leaning states of Arkansas by 5%, Florida by 3.4%, Mississippi by 4.11%, Tennessee by 4.78%, and Texas by 1.92%. The Census Bureau undercounted one Democratic-leaning state, Illinois, by 1.97%.

The Census Bureau overcounted Biden’s home state of Delaware by 5.45% as well as other Democratic-leaning states: Hawaii by 6.79%, Massachusetts by 2.24%, Minnesota by 3.84%, New York by 3.44%, and Rhode Island by 5%. It also overcounted two Republican-leaning states, Ohio by 1.49% and Utah by 2.59%.
