Kathryn Ruemmler, who resigned last week as the top lawyer at Goldman Sachs Group Inc., corresponded with Jeffrey Epstein about a prostitution scandal that engulfed the US Secret Service during her tenure as White House counsel under former President Barack Obama. In a dozen or so exchanges that were sent months after Ruemmler left her White House position in 2014, she complained to Epstein about "this secret service crap" and forwarded to him a draft email that contained detailed, nonpublic information about the behind-the-scenes role the White House Counsel's office played in investigating the 2012 prostitution scandal.
