After a string of court defeats in his efforts to challenge the election results, Mr Trump's team is hoping to convince legislatures controlled by his fellow Republicans in key states to ignore the outcome and declare Mr Trump the victor, according to multiple US media outlets. Mr Trump has also expressed interest in inviting legislators from Pennsylvania, another battleground won by Mr Biden, to the White House, a senior campaign official confirmed to the BBC's US partner, CBS News. But he has no such meetings currently listed on his public schedule for this weekend, and counties in the Rust Belt state, along with Michigan, are due to certify their vote totals on Monday.
