While the source is the correct ProPublica page for MIRI (EIN 58-2565917) and contains the 2023 Form 990 data referenced in the claim, the actual headcount number of 28 is not displayed in the provided excerpt. The source shows compensation for named individuals and financial data, but the specific employee count metric is not present in the text provided. The claim references that this figure comes from 'IRS Form 990' via ProPublica, but the extracted text does not include the headcount field that would typically appear on such a filing. To verify this claim would require accessing the full Form 990 document or a section of the ProPublica page that explicitly lists the employee count.
