“Irresponsible people are spreading lies that are costing people their lives,” the Canadian musician wrote in a statement posted on her website Friday. “I stand in solidarity with Neil Young and the global scientific and medical communities on this issue.”

In a now-deleted statement on his website, Rolling Stone reported that 76-year-old Young said the consequences were “potentially causing death to those who believe this disinformation spread,” adding, “They can have Rogan or Young. Not both.”

Mitchell, known for her songs “Big Yellow Taxi” and “A Case of You,” also cited an open letter to Spotify published earlier this month by a coalition of scientists and medical professionals requesting the implementation of an anti-misinformation policy.

CNN has contacted Spotify and Mitchell’s record company Rhino for comment, but has yet to receive responses.

Rogan has “discouraged vaccination in young people and children, incorrectly claimed that mRNA vaccines are “gene therapy,” promoted off-label use of ivermectin to treat COVID-19… and spread a number of unsubstantiated conspiracy theories,” the authors of the open letter said.

They also said at least two recent guests had “compared pandemic policies to the Holocaust” and said misinformation was “a sociological issue of devastating proportions and Spotify is responsible for allowing this activity to thrive on its platform.”
