WASHINTON– Kathryn Ruemmler, a former Goldman Sachs senior lawyer who was a White House adviser under President Barack Obama, will be questioned before a House committee on Wednesday about her relationship with Jeffrey Epstein.

Ruemmler is the latest prominent figure subpoenaed before the House Oversight Committee as lawmakers investigate the network of powerful people connected to Epstein. The bipartisan investigation has already included testimony from more than a dozen high-profile witnesses, including Microsoft co-founder Bill Gates and former President Bill Clinton, as lawmakers examine how Epstein’s wealth and influence may have helped shield him from scrutiny.

Thousands of documents released by the Justice Department showed that Ruemmler and Epstein had an extensive relationship. The files included personal emails, social plans and gifts that went beyond formal legal work.

Ruemmler served as White House counsel under Obama from 2011 to 2014 and was briefly considered for attorney general. She served as general counsel at Goldman Sachs for the past six years before announcing in February that she would resign amid backlash over her correspondence with Epstein.

The released documents showed the two were close years after Epstein’s conviction for sex crimes in 2008, when he became a registered sex offender. She tried to downplay their relationship in more recent statements, calling him a “monster.” But the documents showed that she had called Epstein “Uncle Jeffrey” in emails and said she adored him.

Although she said she would resign on June 30, she remains employed at Goldman Sachs.

Ruemmler is the 17th person to testify as part of its broader investigation. Billionaire investor Leon Black was subpoenaed last month after lawmakers said he refused to answer questions about his years-long relationship with Epstein.

A committee spokesman said Black’s attorneys confirmed he will appear for a formal deposition on Sept. 3 and will file Black’s confidentiality agreements by the end of next week.

The committee has also expressed interest in questioning acting Attorney General Todd Blanche, whose nomination to permanently lead the Justice Department is pending before the Senate. Former Attorney General Pam Bondi identified Blanche as the department’s point person for the release of Epstein’s documents, a process that has drawn bipartisan scrutiny.
