Updated, Sept. 22The head of the U.S. Department of Health and Human Services, Robert F. Kennedy Jr., is expected to be on Martha’s Vineyard on Tuesday. Indivisible Martha’s Vineyard is leading one protest at the Vineyard airport. Cheryl Andrews-Maltais, chairwoman of the Aquinnah Wampanoag Tribal Council, said that she has served on STAC for 14 years. The Vineyard was selected for this year’s annual meeting, which Andrews-Maltais said will be rewarding for the tribe. Having the meeting in Aquinnah provides policy makers a look into life on the Vineyard specifically, the chairwoman said.
