The Republican-led House Judiciary Committee advanced Wednesday a resolution recommending Hunter Biden be held in criminal contempt of Congress, sending the matter to the full House amid heightened tensions arising from the GOP’s impeachment inquiry into President Biden.

The Oversight and Judiciary Committees gathered separately to consider contempt resolutions targeting Hunter Biden in response to his refusal to comply with congressional subpoenas for closed-door testimony last month. The Judiciary panel approved the measure along party lines in a vote of 23 to 14, while the Oversight Committee is still meeting. If the House takes up and approves the contempt resolutions, federal prosecutors would decide whether to charge the president’s son.

The meeting of the Oversight Committee saw an unexpected appearance by Hunter Biden himself, who sat before lawmakers with his lawyer Abbe Lowell for roughly 30 minutes as members delivered opening remarks. The meeting took a chaotic turn with his attendance, as Republicans hurled insults at Hunter Biden directly. Lawmakers later squabbled over whether the GOP’s investigation had produced evidence implicating the president and engaged in shouting matches with one another at various times.
