(Refiles to fix Weiss's title in paragraph 4)

WASHINGTON (Reuters) -U.S. President Joe Biden's son, Hunter Biden, will appear in a federal court in Wilmington, Delaware, on Sept. 26 to face gun charges, a judge ordered on Wednesday.

Hunter Biden, 53, was indicted last week for allegedly lying on a form to acquire a handgun in 2018 and for being an illegal drug user in possession of the gun. His lawyer has said he plans to plead not guilty.

Hunter Biden sought to avoid traveling to Delaware to appear for the hearing in person, arguing it would pose logistical challenges, but U.S. District Judge Maryellen Noreika rejected his request to appear by video.

U.S. Special Counsel David Weiss, who is prosecuting the case and has conducted a wide-ranging investigation of Hunter Biden, opposed allowing Biden to appear by video for the routine proceeding. He said an in-person hearing would promote the "public’s confidence that the defendant is being treated consistently with other defendants."

The hearing was set on the same day U.S. Attorney General Merrick Garland appeared before a U.S. House committee, where he faced hours of questioning about the Justice Department's handling of the Hunter Biden probe.

The younger Biden was set to enroll in a program to avoid prosecution on a gun charge as part of a broader plea deal, but the agreement collapsed under questioning from the judge.

The trial means that the United States will likely face the unprecedented spectacle of a sitting president's child facing a criminal trial while his father campaigns for re-election. Biden's likely Republican rival, Donald Trump, also faces four upcoming criminal trials of his own.
