The US Congress formally certified Republican President-elect Donald Trump's election victory on Monday during a session presided over by Democratic Vice President Kamala Harris.

The quadrennial ritual, clearing the way for Trump's inauguration in two weeks, went like clockwork and stood in sharp contrast to four years ago when a mob of Trump supporters stormed the Capitol in a failed bid to block the certification of then-President Trump's 2020 loss to Democratic President Joe Biden.

Donald Trump is scheduled to be sworn in as the President of the United States for a second term on January 20.
