Congressional testimony from a former JP Morgan Chase executive has put the bank's long relationship with Jeffrey Epstein back under scrutiny, and it looks bad for the bank.

• Jes Staley told the House Oversight Committee about 2010 emails with Epstein referring to a woman by the code name "Snow White."
• Lawmakers who saw the unredacted files say Epstein had that same woman buy a Snow White costume, and a message the next day described her having sex twice.
• Staley denied sex with that woman but admitted one encounter with an adult Epstein staffer who later sued Epstein and settled with his estate.
• He also confirmed visiting Epstein's island three times and his townhouse dozens of times.
• The money angle: JP Morgan suspected Epstein of human trafficking by 2011 and kept him as a client anyway, raising the question of how much leverage Epstein held over the executive handling him.

Outlook: Expect more pressure on JP Morgan over why it kept Epstein's business, and continued fights over the still-unreleased material in the files.
