WASHINGTON: "When President Joe Biden takes the rostrum Wednesday to deliver his first address to a joint session of Congress, he’ll have a live audience that looks substantially different than his predecessors faced, including a much smaller contingent of the Supreme Court. A spokeswoman for the nation’s highest court confirmed Monday that only Chief Justice John Roberts will attend the address. Roberts, spokeswoman Kathleen Arberg said, was the only one of the nine justices invited due to COVID-19 social distancing protocols."
