[1/2] The U.S. Supreme Court building is seen in Washington, U.S., June 26, 2022.
The Senate has the authority to confirm a president's nominees to the federal judiciary including the Supreme Court.
Biden's Republican predecessor Donald Trump put a major emphasis on getting judicial nominations confirmed as he worked to move the judiciary rightward.
If Democrats retain control, Biden has a chance to match or surpass Trump's mark of having 234 judicial nominees confirmed over four years.
Circuit courts are the regional federal appellate courts one step below the Supreme Court.
