Trump's campaign manager Bill Stepien says they will demand that the votes in Wisconsin be recounted.
At the same time, the Trump campaign demands that they try to stop the vote counts in Michigan and Pennsylvania.
The motivation is that the Trump campaign wants better transparency with its observations.
"Observing means being able to look, but no one has been allowed to look," said Rudy Giuliani, Trump's legal representative at a news conference in Philadelphia.
Step one: State courts
Forecasts say the Wisconsin margin will be less than one percentage point between the two candidates.
This means that the losing candidate can request a recalculation of the votes.
But it can not be done until after December 1, when the election result from Wisconsin becomes official, says Henrik Ekengren Oscarsson, election researcher and professor of political science.
As for the lawsuit to stop the counting of votes in Michigan due to lack of transparency, it will be a matter for a state court.
- We do not know which legal space they are referring to, but I assume that there will be a negotiation about this.
The process began similarly in Florida in 2000, in a state court, says Dag Blank, professor of North American studies, in SVT's Aktuellt.
Then: The Federal "Supreme Court"
Only after the various complaints have been dealt with by state courts can the national and federal Supreme Court deal with the cases.
In his rhetoric on Wednesday, Trump threatened to go directly to the Supreme Court.
- It is difficult to know what he means, because it is not possible at once, says Dag Blank.
- They have filed a lawsuit in Michigan and it is the states that handle the election laws.
If he wants to question the election result, he must do so in the state, says Blank.
Deadline: December 14
The people's election results in the so-called electors being appointed and who in turn appoint the president.
On December 14, electors from the various states will vote for the president.
- They must meet then and they must be in place, says Dag Blank.
If they do not?
- Then a very unclear situation arises.
Every effort will be made to make it happen and that was one of the reasons why the Supreme Court stopped the bill in Florida in 2000.
Other scenarios: "Lively imagination"
Henrik Ekengren Oscarsson does not rule out that other things may happen in the continued vote count.
- People have a lively imagination so anything can happen.
But hopefully a clear election result is not far off.
On Friday, I think we will have a good picture of who actually won, says Ekengren Oscarsson.
