唔知有冇人提過, 憲法上係由現任副總統aka senate president 去宣佈新總統當選人
(當年就係由pence去announce biden president elect).
Under the U.S. constitution, a vice president is automatically president of the Senate and it is the role of the
Senate president to officially declare the result of a presidential election.
As the Senate website explains: "The Constitution names the vice president of the United States as the president of the Senate. In addition to serving as presiding officer, the vice president … formally presides over the receiving and counting of electoral ballots cast in presidential elections.
