The House Oversight Committee has served subpoenas to a billionaire investor who made payments to Jeffrey Epstein. House lawmakers questioned Leon Black on Friday in a voluntary interview about his Epstein ties, but they say he refused to answer some questions. Black denied any criminal wrongdoing in his opening statements and claimed he was deceived by Epstein. Black was formerly the chief executive of Apollo Global Management and paid Epstein $158 million from 2012 to 2017 for tax and estate planning services. Lawmakers told reporters that Black refused to answer questions about non-disclosure agreements. They issued subpoenas for documents and for Black to testify under oath in July.
