Donald Trump's presidential win is going to be certified in Congress in January by the candidate he beat, Vice President Kamala Harris .
Under the Constitution, the vice president is the head of the Senate, and it's the role of the Senate president to declare the result of a White House election.
That happens Jan. 6.
Under normal circumstances, the vote-tallying procedure performed by the vice president is a mere formality and it's the final step in the complicated technical process of electing a new administration.
For example, in 2000, after the grueling 36-day Florida recount battle, Democrat Al Gore conceded the presidency on Dec. 13 to Republican George W. Bush.
