//Three of Trump’s challenges in Arizona, Pennsylvania and Michigan have failed.//
From where did you get that ?
From the wicked BBC (and there are doubtless other challenges ongoing):
“However, Mr Trump's efforts to overturn the result suffered three setbacks on Friday:
In Arizona, his team dropped a lawsuit seeking a review of ballots cast on Election Day after it became clear his rival's lead was unassailable. The challenge was based on a claim that some legal votes had been rejected
In Michigan, a judge rejected a request by two Republican poll watchers - who had alleged fraud in Wayne County - to block the certification of election results in Detroit
In Philadelphia, Pennsylvania, the Trump campaign's requests to invalidate several batches of mail-in ballots were rejected”
