House Republicans plan to move forward next week with holding Hunter Biden in contempt of Congress after the president’s son defied a congressional subpoena to appear for a private deposition last month.

The Republicans who lead the House Oversight and Accountability Committee and the Judiciary Committee announced Friday that they will hold votes on contempt charges against Hunter Biden as the GOP moves into the final stages of its impeachment inquiry. If the committees approve the charges, the full House would get a final vote.

“Hunter Biden’s willful refusal to comply with our subpoenas constitutes contempt of Congress and warrants referral to the appropriate United States Attorney’s Office for prosecution,” said Reps. James Comer, R-Ky., and Jim Jordan, R-Ohio, in a joint statement. “We will not provide him with special treatment because of his last name.”

Hunter Biden and his lawyers have repeatedly slammed the GOP-issued subpoena for the closed-door testimony, arguing that information from those interviews can be selectively leaked and manipulated. Hunter Biden has insisted that he would only testify in public.
