Jack Schlossberg asked his in-law if she could “call up the family of the child who died of measles and say sorry."

John F. Kennedy’s grandson Jack Schlossberg is trolling his uncle Robert F. Kennedy Jr.’s wife Cheryl Hines for the recent—and incredibly rare—death of a child from measles in the U.S. Schlossberg took to Instagram less than a month after deleting his accounts as some sort of penance for insulting his uncle’s voice.

Jack Schlossberg, JFK's grandson, shared multiple social media videos imploring RFK Jr.'s wife, actress Cheryl Hines, to contact the family of the child who died from the measles outbreak in Texas and apologize.
