“This is a scam by the Green Party for an election that has already been conceded, and the results of this election should be respected instead of being challenged and abused, which is exactly what Jill Stein is doing,” Trump said in a statement.

Citing concerns that voting systems have been compromised, Stein filed for a recount in Wisconsin on Friday afternoon, and has been fundraising off her vow to do the same in Pennsylvania and Michigan — all states in which Trump won or is leading.

On Saturday, Hillary Clinton’s general counsel Marc Elias said that the campaign would be participating in the Wisconsin recount, though they had discovered no evidence that the voting process had been interfered with. He said the campaign would join the effort in the other states if Stein continued pushing for a recount there.
