House Oversight Chairman James Comer (R-KY) signaled Monday that the panel could expand its subpoena list in its investigation of Jeffrey Epstein, after Democrats pressed to hear from former Labor Secretary Alex Acosta.

Acosta, who served as U.S. attorney in Florida before joining President Donald Trump’s first-term Cabinet, has long faced scrutiny for approving Epstein’s lenient 2008 plea deal, which allowed him to avoid federal charges and serve just 13 months in a county jail with work-release privileges. The agreement was kept hidden from victims, a decision a federal judge later ruled violated the Crime Victims’ Rights Act.
