A group of women who survived abuse by Jeffrey Epstein are urging Congress to pass legislation that would force Donald Trump’s administration to hand over banking records that could expose the financial engine behind the late sex offender.

The bill introduced by Democratic Sen. Ron Wyden would compel the Treasury Department to turn over documents to Senate investigators who have been digging into Epstein’s financial network for several years. The Treasury Department is cooperating with a House committee’s similar request.
