Washington: US congress formally certified Joe Biden as the next US President on Thursday. The affirmation of Biden’s 306-232 victory over Trump in November essentially closes the door on the unparalleled and deeply controversial effort by Trump and his loyalists to overturn the results of the 2020 election.

Lawmakers in the Senate and House of Representatives successfully beat back Republican efforts to deny Biden the electoral votes needed to win, prompting loud cheers when the certification was announced.

Egged on in an extraordinary rally across town by an aggrieved Trump, a flag-waving mob had broken down barricades outside the Capitol and swarmed inside, rampaging through offices and onto the usually solemn legislative floors. Security forces fired tear gas in a four-hour operation to clear the Capitol. Police said that one woman, reportedly a female Trump partisan from southern California, was shot and killed and that three other people died in the area in circumstances that were unclear.
