Sen. Bernie Sanders (I., Vt.), thought to be a possible “yes” vote on Robert F. Kennedy Jr. because they have some shared views on food safety and obesity, grilled Kennedy on his views on abortion and vaccines.

Senator Bernie Sanders from Vermont ripped into possible Health and Human Services Secretary Robert F. Kennedy Jr. on Wednesday after the man failed to answer as to whether or not healthcare was a basic human right.

Sen. Bill Cassidy, the top Republican on the Senate Committee on Health, Education, Labor and Pensions, concluded Thursday's hearing by saying he was "struggling" with the nomination due to Kennedy's vaccine positions. Kennedy notably refused to say vaccines don't cause autism as he faced pointed question from lawmakers.
