President Biden Urged to Accept and Acknowledge Seventh Grandchild

The author's Republican sister voted for Biden in the past but now wants him to accept his seventh grandchild, Navy Joan.
Navy Joan is the daughter of Hunter Biden but he has shown little interest in her.
Public figures who have embraced children from previous relationships are contrasted with Biden's treatment of Navy.
Biden's actions contradict his emphasis on family and empathy according to the author who wants Biden to embrace Navy.
The overall argument is that Biden should recognize Navy as part of his family.
