Hillary Clinton’s campaign said Saturday it will take part in efforts to push for recounts in several key states, joining with Green Party candidate Jill Stein, who has raised millions of dollars to have votes counted again in Wisconsin.

But, in a post on Medium, Marc Elias, the campaign’s counsel, said the campaign’s own investigation has not uncovered any evidence of hacking of voting systems.

In the campaign’s most detailed comments to date on the recount, Elias wrote that while the campaign was not going to contest the results itself, it has decided now to take part in the effort to “ensure that it is fair to all sides.”
