Protesters at a U.S. Senate hearing on Wednesday were escorted out after disrupting the hearing proceedings where U.S. Health and Human Services Secretary Robert F. Kennedy, Jr. was testifying. Democrats and Republicans alike raised concerns about deep staffing cuts, funding freezes and far-reaching policy changes overseen by Kennedy. Kennedy was pressed repeatedly on the mixed message he’s delivered on vaccines, which public health experts have said are hampering efforts to contain a growing measles outbreak now in at least 11 states.
