Mitch McConnell warns RFK Jr. against effort to undermine polio vaccines

Senate Republican Leader Mitch McConnell issued an apparent warning Friday to Robert F. Kennedy, President-elect Donald Trump's pick to lead the Health and Human Services Department, after The New York Times reported that one of Kennedy's top advisers had filed petitions to revoke the approval of a polio vaccine and several other shots. 

"Anyone seeking the Senate's consent to serve in the incoming Administration would do well to steer clear of even the appearance of association with such efforts," McConnell said in a statement.

McConnell, a polio survivor, denounced efforts "to undermine public confidence in proven cures" like the polio vaccine.
