U.S. Vice President Mike Pence signaled support on Saturday for a futile Republican bid to overturn the election in Congress this week, after 11 Republican senators and senators-elect said that they would vote to reject President-elect Joe Biden’s victory when the House of Representatives and Senate meet to formally certify it.

The announcement by the senators — and Pence’s move to endorse it — reflected a groundswell among Republicans to defy the unambiguous results of the U.S. election and indulge President Donald Trump’s attempts to remain in power with false claims of voting fraud.

Every state in the country has certified the election results after verifying their accuracy, many following postelection audits or hand counts. Judges across the country, and a Supreme Court with a conservative majority, have rejected nearly 60 attempts by Trump and his allies to challenge the results.
