What legal challenges is Trump planning?
Trump’s lawyer Rudy Giuliani told Fox News that it would be wrong for Mr Trump to concede because: “There is strong evidence that this was an election that in at least three or four states, and possibly 10, it was stolen.”
The Trump campaign is yet to provide this “strong evidence”.
Pennsylvania
Giuliani says further lawsuits will be filed over a lack of access for poll watchers in the state.
Wisconsin
The president’s campaign has said it will request a recount in Wisconsin “based on abnormalities seen” on election day, although this wouldn’t require a lawsuit.
It’s unclear when this recount would take place, since typically these don’t happen until after officials finish reviewing the votes. The state’s deadline for this part of the process is 17 November.
Nevada
The Nevada Republican Party tweeted saying: “Thousands of individuals have been identified who appear to have violated the law by casting ballots after they moved from Nevada.”
The case is focused on voters in Clark County, but the county’s registrar has said: “We are not aware of any improper ballots that are being processed.”
Arizona
The Trump campaign filed a lawsuit in Arizona on Saturday, claiming some legal votes were rejected.
The case cites declarations by some poll watchers and two voters who claim they had problems with voting machines.
The lawsuit is under review, but Arizona’s Secretary of State said it was “grasping at straws”.
What legal challenges by Trump have been dismissed?
Michigan
On 4 November, the Trump campaign filed a lawsuit to stop the count over claims of a lack of access to observe the process.
A judge dismissed the lawsuit, saying there was insufficient evidence that oversight procedures weren’t being followed.
Nevada
In a separate case, a federal judge blocked attempts by the Republicans to stop the use of a signature verification machine, rejecting allegations that it wasn’t able to check signatures correctly.
Georgia
A lawsuit was filed in Georgia’s Chatham County to pause the count, alleging problems with ballot processing.
On 5 November, a judge dismissed this lawsuit, saying there was “no evidence” of improper ballot mixing.
