Members of Congress on Friday explored ways to increase transparency and accountability of the federal judiciary, though some voiced concern that reforms could jeopardize the security of judges and the unique status of Supreme Court justices.

“As both branches consider how to ensure that the judicial branch keeps pace with our evolving standards for transparency and accountability in a modern democracy, we must be mindful of the safety of our judges and the women and men who assist the courts in fulfilling their responsibilities,” House Judiciary Committee chairman Jerrold Nadler, D-New York, said in a statement.
