U.S. presidential candidate Hillary Clinton's campaign has said it will take part in a recount of election votes in the state of Wisconsin.
U.S. President-elect Donald Trump, the shock winner of the November 8 election, said the recount was a "scam."
Wisconsin's election board on November 25 approved the recount requested by Green Party candidate Jill Stein, who cited "statistical anomalies" in Wisconsin. Stein is also seeking recounts in the states of Michigan and Pennsylvania.
In a statement, Trump said the recount is a "scam by the Green Party for an election that has already been conceded."
"The results of this election should be respected instead of being challenged and abused," he added.
Marc Elias, the Clinton campaign counsel, said the campaign had not found any signs of hacking of voting systems but would take part in the recount "in order to ensure the process proceeds in a manner that is fair to all sides."
The voting margins make it highly unlikely any recounts would give Clinton a victory in all three states, which would be needed to alter the outcome of the election.
