EXCLUSIVE — Federalist Society co-Chairman Leonard Leo said Thursday he is “not capitulating” after he announced Sen. Dick Durbin (D-IL) filed a subpoena against him.

“Today, I received an unlawful and politically motivated subpoena from U.S. Senate Judiciary Committee Chairman Dick Durbin,” Leo said in a statement obtained by the Washington Examiner. Last November, the Democratic-led committee held a vote to authorize subpoenas for GOP megadonor Harlan Crow and the Federalist Society co-chairman, the latter of which has long been criticized by liberal activists for his role in influencing the federal judiciary.
