President Biden's sister, Valerie Biden Owens, arrives at court

President Biden's sister, Valerie Biden Owens, entered the court in Wilmington, Delaware where his son Hunter is on trial at 8:11 a.m. ET on Friday.

Biden family members including First Lady Jill Biden have attended the trial to show support for Hunter Biden as he faces criminal charges for allegedly making false statements on a federal form when he purchased a gun in 2018.

"Of course the family is there en masse," a close family friend who has attended the trial each day told NBC News. "Imagine if this was your son, your brother. This is their family. Their beloved family.”

Many family and friends attended the trial in support of Hunter Biden, including President Joe Biden’s longtime friend, Richard Smith, president of Delaware’s NAACP branch.

The case will hinge on whether Hunter Biden knowingly lied on a federal gun application, which prompted prosecutors to heavily refer to his memoir, “Beautiful Things,” and play numerous excerpts from the audiobook as the only testimony from Hunter Biden that the jurors might hear.
