Kennedy cousin Michael Skakel is expected at a court hearing Friday as Connecticut prosecutors decide whether to retry him for the bludgeoning death of a fellow teenager in 1975. The nature of the hearing wasn't clear as the case remains sealed under a state juvenile offender law. Justices said in the new 4-3 ruling that Skakel’s trial lawyer failed to present an alibi witness. Several other people, including Skakel’s brother Tommy Skakel who denied any role in the killing, have been mentioned as possible killers. At Skakel’s trial, prosecutors suggested Skakel was angry with Martha because she had spurned his advances while having a sexual liaison with his brother Tommy.

OAKLAND, Calif. – Facebook says it will ban ads on its platform that discourage vaccinations — with an exception carved out for advocacy ads about government vaccine policies. The company already bans ads about vaccine “hoaxes," such as the false idea that vaccinations cause autism. The latest policy expands the ban to ads that discourage vaccines for any reason. And unpaid posts by people or groups that discourage vaccinations will also still be allowed — the new policy only includes paid advertisements. “Facebook by banning anti-vaccine ads is probably not banning more than half of the ads,” he said.

About 120 Kennedy family members held a prayer service on the Zoom video-conferencing app over the weekend for Maeve Kennedy McKean and her 8-year-old son, Gideon, who are presumed dead after disappearing while canoeing last week. David McKean, the husband of Maeve and father of Gideon, said Friday that it's "clear" his wife and son "have passed away." Robert F. Kennedy Jr., the brother of McKean's mother, Kathleen Kennedy Townsend, posted images on Instagram of the prayer service, which he said was led by Timothy Shriver, a cousin. Kennedy Jr. said the service was attended by "Kennedy / Shriver / Lawford / McKelvey/ Allen / Schlossberg/ Schwarzenegger / Cuomo cousins." On Friday, Maeve's mother, former Maryland Lieutenant Governor Kathleen Kennedy Townsend, said the search had "turned from rescue to recovery."
