Here are the rules for a recount in the American Presidential election's battleground states

President Donald Trump's campaign said on Wednesday it would immediately request a recount in Wisconsin, even though the state has not yet finalized its results. Both CNN and the Associated Press projected that Democrat Joe Biden won the key battleground state's 10 electoral votes. Edison Research said the margin between Biden and Trump was less than 1 percentage point, meaning a candidate can request a recount.

Below is a roundup of recount laws in Wisconsin and some other battleground states:
