Beyond the protesting spectators and U.S. senators quarreling over access to documents, Senate Judiciary Republicans and Democrats revealed Tuesday the contentious issues that will be fought over as Brett Kavanaugh’s confirmation hearing to the U.S. Supreme Court heads into its second day.

Kavanaugh sat stone-faced throughout much of Tuesday’s hearing, as senators from both sides sparred over the merits of his nomination. He only occasionally cracked a smile. There were no head nods, no eye rolls. Kavanaugh choked up at the end of his opening statement, in which he vowed to keep an open mind in every case that might come before him on the Supreme Court.
