A judge in Pennsylvania has dismissed a lawsuit from the Trump campaign that sought to invalidate millions of mail-in votes in the battleground state.
Judge Matthew Brann said the lawsuit, which rested on allegations of irregularities, was "without merit".
The move paves the way for Pennsylvania to next week certify Joe Biden's win - he leads by more than 80,000 votes.
It is the latest blow to Donald Trump, who is trying to overturn his loss in the 3rd November presidential election.
Trump has refused to concede and made allegations of widespread electoral fraud, without providing any evidence.
The lack of a concession has upended the process that normally follows a US election. Naveel
