Jack Schlossberg, the only grandson of President John F. Kennedy, was not among the many people poring over the new trove of government files about Kennedy’s assassination when it was released Tuesday. Instead, Schlossberg was on social media criticizing President Donald Trump, Republican lawmakers and the news media over the handling of the files.

Jack Schlossberg, the only grandson of the 35th U.S. president, said that the Kennedy family had not been notified, with exception of Health Secretary RFK Jr.

Jack Schlossberg, former President John F. Kennedy’s grandson, called out President Trump and Health and Human Services Secretary Robert F. Kennedy Jr. over the release of close to 2,200 files on his grandfather’s assassination.
