U.S. Supreme Court Chief Justice John Roberts said on Tuesday that the court is considering steps to "adhere to the highest standards of conduct," after reports of a conservative justice's travel and real estate deals prompted congressional scrutiny.
Roberts, speaking at an event hosted by the American Law Institute, said that he is "committed" to ensuring the court's nine members meet those standards. He did not give details on what those measures would look like.
But the chief justice also signaled that he is wary of potential legislation by Congress that could impose an ethics code for the justices.
Roberts said he is "confident there are ways" to make sure the court's members are meeting their ethical obligations "that are consistent with our status as an independent branch of government under the Constitution's separation of powers."
It was the first time Roberts has publicly commented since a U.S. Senate committee hearing earlier this month on a potential ethics code for the high court. The U.S. Supreme Court is the only federal court in the United States that does not have a formal ethics code.
While Senate Democrats on the panel have backed potential ethics legislation, Republican members have staunchly opposed it.
The news outlet ProPublica has detailed ties between Justice Clarence Thomas, a conservative who is the court's longest-tenured member, and wealthy Republican donor Harlan Crow.
Crow's attorneys this week rejected a bid by Senate Democrats to learn of other gifts given by the Dallas billionaire to Thomas. They argued that Congress lacks the authority to impose an ethics code on the justices.
