President-elect Donald Trump, who called the presidential elections "rigged" for most of his campaign, branded the recount effort aimed at revisiting the vote in three pivotal battleground states a "scam".
"The people have spoken and the election is over," Trump declared on Saturday in his first comments about the growing effort to force recounts in Wisconsin, Michigan and Pennsylvania.
He added, "We must accept this result and then look to the future."
Later on Saturday he also accused the Green Party of trying to "fill up their coffers" with an "impossible recount".
Green Party nominee Jill Stein's fight for a recount got a major boost on Friday when Wisconsin officials announced they were moving forward with the first presidential recount in state history.
The incoming president had been paying little if any attention to Stein's recount push, but Democratic rival Hillary Clinton forced his hand on Saturday by formally joining the effort .
Stein, who drew 1 percent of the vote nationally, is raising millions of dollars to fund the recounts.
"Because we had not uncovered any actionable evidence of hacking or outside attempts to alter the voting technology, we had not planned to exercise this option ourselves," Clinton campaign lawyer Marc Elias wrote on Saturday in a blog post.
"But now that a recount has been initiated in Wisconsin, we intend to participate in order to ensure the process proceeds in a manner that is fair to all sides," Elias stated.
Elias said Clinton would take the same approach in Pennsylvania and Michigan if Stein were to follow through with recount requests in those states, even though that was highly unlikely to change the election outcome.
Clinton leads the national popular vote by close to 2 million votes, but Trump won 290 electoral votes to Clinton's 232, with Michigan still too close to call. It takes 270 to win the presidency.
Trump, who repeatedly challenged the integrity of the election system before his win, called the recount push "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, which is exactly what Jill Stein is doing," he said in the statement, which did not mention Clinton's involvement.
Trump was expected to return to New York on Sunday after spending the Thanksgiving holiday weekend at his West Palm Beach estate. His transition team said the president-elect had scheduled a series of Monday meetings with prospective administration hires.
'Fidel Castro is dead'
Trump offered a one-line tweet on Saturday morning in reaction to the death of Cuban leader Fidel Castro - "Fidel Castro is dead!" - before issuing a more detailed statement.
"While Cuba remains a totalitarian island, it is my hope that today marks a move away from the horrors endured for too long, and toward a future in which the wonderful Cuban people finally live in the freedom they so richly deserve," Trump said.
A more restrained President Barack Obama, carefully promoting and working to preserve his own attempt to rebuild those ties, said history would assess Castro's impact and that the Cuban people could reflect "with powerful emotions" about how their longtime leader influenced their country.
Trump's Cuba policy was inconsistent during the campaign.
He first suggested he supported President Barack Obama's orders loosening the US trade embargo on the island.
He reversed himself less than a month before the election, however, vowing to overturn Obama's order unless Cuba meets demands including "religious and political freedom for the Cuban people and the freeing of political prisoners".
