A judge appointed Michael Jackson’s nephew on Wednesday to share guardianship responsibilities for the singer’s three children, but not without a last-minute effort by some relatives to delay the decision. Superior Court Judge Mitchell Beckloff named TJ Jackson as the children’s co-guardian who will now share responsibilities for raising the siblings, who range in ages from 10 to 15. The judge made the ruling after considering a letter submitted by singer Diana Ross, who was named in Michael Jackson’s will as a potential guardian, and a letter presented by cousins of the singer who sought a delay in the appointment. Debra Jackson and her son Anthony urged Beckloff to delay his ruling, saying they were concerned that family matriarch Katherine Jackson was being coerced. The pair said they had been ostracized from the family and that the children may not be as excited about TJ Jackson’s appointment as has been presented to the judge.
