House Oversight Chair James Comer shifted Epstein investigation proceedings from formal hearings to informal roundtables that don't require witnesses to testify under oath, according to a Democratic memo confirmed by multiple news outlets. Democrats argue this strips the investigation of legal teeth and prevents them from forcing subpoena votes, though Republicans dispute this characterization of their intent. The core procedural change is documented fact; whether it effectively 'kills' the investigation or represents legitimate scheduling flexibility is contested between the parties.
