A former assistant to Jeffrey Epstein appears to have played a much more damning role than Republicans would like to believe, alleged a Democratic member of the House Oversight Committee."Sarah Kellen comes up a lot," said Rep. Suhas Subramanyam (D-VA) said Saturday on MS NOW, speaking about the Epstein files. "She was essentially a gatekeeper for Epstein. She was paramount in making him available to be able to do these heinous crimes."The House Oversight Committee has scheduled Kellen, who started working as Epstein's assistant in 2000, to testify May 21 in a transcribed interview as part of its investigations into the disgraced financier's connections.Subramanyam, a member of the committee, explained that Kellen is "unique" as she was "essentially an executive assistant, a scheduler and an operator for a lot of Jeffrey Epstein's activities."Committee Chairman James Comer (R-KY) has characterized Kellen and other women in Epstein's orbit as victims, which Subramanyam concedes is likely accurate, but he added that "from what I've seen in the [Epstein] files, she's more co-conspirator to me than anything else because of how involved she was.""She knew all about his crimes," Subramanyam continued. "We'd love to know what Sarah Kellen knows. We'd love to know if Sarah Kellen can explain to us how Jeffrey Epstein was able to get away with these crimes."
