Donald Trump became the 47th President-elect of the United States on Wednesday, defeating Vice President Kamala Harris in the race for the White House. Looking forward, Trump will be officially sworn in on Jan. 20, but before that happens, Harris will have to preside over the certification of the electoral votes in Congress.
The sitting vice president, Harris in this case, serves as the president of the Senate. Hence, they are constitutionally-bound to oversee the certification of Trump's win by Congress on Jan. 6, meaning she will certify her own loss when the time comes.
