Hunter Biden ignored questions Monday concerning his father, President Joe Biden, refusing to acknowledge his unclaimed 4-year-old granddaughter born out of wedlock to ex-stripper Lunden Roberts.

As he left a Batesville, Arkansas, courthouse for a lunch break amid a child support hearing for his daughter, Navy Joan Roberts, Fox News Digital asked Hunter whether his father was doing a disservice by not recognizing his grandchild, but Hunter did not give an answer.

Hunter was ordered to appear in person for the hearing after the child support case was reopened when he requested adjustments to the child support payments. The older Roberts had previously reached an agreement with Hunter Biden in 2020 for the child's paternity and child support payments.

In December, her lawyers filed a motion to have the girl's last name changed to Biden.

On numerous occasions, President Biden has refused to acknowledge his granddaughter. This happened most recently at a White House Take Your Kids To Work event last week when he told the crowd that he speaks to his six grandchildren daily and is "crazy" about them, according to one White House reporter. Roberts is his seventh grandchild.

Additionally, December 2022 marked the second Christmas season in a row that the White House left Hunter's out-of-wedlock daughter out of a Christmas stocking display.

And before that, in 2020, Biden said he and wife Jill Biden had five grandchildren, forgetting about a newborn that Hunter just had with his wife, Melissa Cohen.
