A co-chair of Donald Trump’s transition team said Trump supporter Robert F. Kennedy Jr. wants access to federal health data so he can show vaccines are unsafe and lead to them being pulled from the market in a second Trump administration.

Howard Lutnick echoed a number of Kennedy’s debunked anti-vaccine talking points in a CNN interview Wednesday, including falsehoods about the vaccine schedule and the disproven theory that vaccines cause autism. Trump has talked often about how Kennedy, who suspended his own presidential bid and endorsed him in August, will have a big role to play if the former president returns to the White House.
