U.S. Rep. Mark Pocan (D-Wis.) asked Kennedy during a House Appropriations Committee hearing on Wednesday whether he would choose to vaccinate his children against measles. Kennedy, a longtime vaccine skeptic, dodged the question, then stated that Americans should not be taking “medical advice” from him.
