What responablity does the chief justice have in an impeachment of a present?

In an impeachment trial of a president, the Chief Justice of the United States presides over the Senate proceedings. This role includes maintaining order, ensuring that the trial follows established rules, and guiding the Senate in its deliberations. The Chief Justice does not vote on the articles of impeachment unless there is a tie. Their presence is intended to lend a sense of impartiality and legitimacy to the proceedings.
