Conservative judicial activist Leonard Leo said he will not comply with a subpoena issued by Democrats on the Senate Judiciary Committee as part of their ongoing investigation into ethics practices at the Supreme Court.

The subpoena was issued to Leo by Judiciary Committee Chairman Dick Durbin on Thursday, months after Democrats on the panel voted to authorize it. Durbin has been looking into ethics issues at the high court for roughly a year following a series of reports that revealed Justice Clarence Thomas took luxury trips with a Republican megadonor, Harlan Crow, and did not disclose them. Crow, a Texas real estate developer, did not receive a subpoena from Durbin, a spokesman for Crow said. ...

"I am not capitulating to his lawless support of Senator Sheldon Whitehouse and the left's dark money effort to silence and cancel political opposition," Leo, who has played a crucial role in the confirmations of several of the conservative Supreme Court justices, said in a statement. Leo is the co-chairman of the conservative Federalist Society.
