FOX NEWS -- President Donald Trump's return to the White House could clear the way for the public to finally see a glimpse of Jeffrey Epstein's long-awaited "black book," as questions about the deceased financier and sex trafficker continue to swirl years after he was found dead in a federal jail in New York City.

Sen. Marsha Blackburn, a Tennessee Republican who has long called for the government to release more of its evidence against Epstein and his potential accomplices, raised the issue during a Senate confirmation hearing Thursday for Trump's FBI director nominee, Kash Patel.

"I have been working on this for years, trying to get those records of who flew on Epstein's plane and who helped him build this international human trafficking, sex trafficking ring," Blackburn told the nominee.
