Hunter Biden unexpectedly made a short appearance at a Capitol Hill hearing Wednesday as House Republicans were starting the process of holding the president鈥檚 son for not complying with a congressional subpoena to sit for a closed-door deposition last month.

Both the House Oversight and House Judiciary committees, which subpoenaed the president鈥檚 son for his testimony as part of the impeachment inquiry into President Joe Biden, are holding separate markups of the contempt resolution. Hunter Biden walked through the halls of Congress with his lawyers outside the Oversight Committee hearing, creating a tumultuous scene inside and outside the committee room as lawmakers debated what to do.

Hunter Biden entered the committee room and sat down for around 10 minutes before departing.

"You are the epitome of White privilege鈥 said GOP Rep. Nancy Mace of South Carolina. 鈥淐oming into the Oversight Committee, spitting in our face, ignoring a congressional subpoena to be deposed. What are you afraid of? You have no balls."

The allegations at the core of the Republican-led investigation stem from that the president was involved in or financially benefited from his son鈥檚 foreign business dealings, making the president鈥檚 son a crucial witness for their probe.

Hunter鈥檚 appearance was reminiscent of how he approached the subpoena last month. Instead of sitting for his deposition, outside the Capitol and has said he will only testify in a public setting. House Republicans maintained they were willing to hold a public hearing with the president鈥檚 son, but only after he sat for a private interview. After the younger Biden did not appear for his deposition, House Oversight Chair James Comer and House Judiciary Chair Jim Jordan issued a joint statement announcing they would begin contempt proceedings.

In a statement, Hunter Biden鈥檚 lawyer Abbe Lowell said they offered to engage with House Republicans on Oversight six times but allege instead, Comer sought a subpoena for a closed-door deposition.

鈥淚gnoring that invitation and proving again that they cared little for the truth and wanted only to 鈥榤ove the needle of political support鈥 that Chairman Comer confessed was his purpose, the Republican chairs have today commandeered an unprecedented resolution to hold someone in contempt who has offered to publicly answer all their proper questions,鈥 Lowell said. 鈥淲hat are they afraid of?鈥

Hunter Biden鈥檚 appearance is part of a  that his legal team, led by lawyers Lowell and Kevin Morris, has adopted to confront his detractors. The lawyers are aware that despite Congress holding a contempt vote against him as early as next week, they have few 鈥 if any 鈥 ways to enforce a punishment. Biden鈥檚 ability to hold off congressional testimony has become even greater in recent weeks, because he now faces both criminal tax and gun charges, according to a source familiar with the negotiations.

TENSIONS BOIL OVER AT OVERSIGHT HEARING

In the Oversight hearing, Democratic Rep. Jared Moskowitz of Florida responded to Mace鈥檚 taunts of the president鈥檚 son by saying, 鈥淚f the gentlelady wants to hear from Hunter Biden we can hear from him right now.鈥

Mace shot back: 鈥淚 think that Hunter Biden should be arrested right here right now and go straight to jail.鈥

When GOP Rep. Marjorie Taylor Greene of Georgia started speaking, Hunter Biden and his attorneys left the room.

鈥淚 think it鈥檚 clear and obvious for everyone watching this hearing today that Hunter Biden is terrified of strong, conservative, Republican women because he can鈥檛 even face my words as I was about to speak to him,鈥 Greene said.

Reacting to all of the members interrupting each other, GOP Rep. Andy Biggs of Arizona implored his colleagues 鈥渄on鈥檛 act like a bunch of nimrods.鈥

Comer, a Kentucky Republican, kicked off the hearing defending his panel鈥檚 subpoena for a closed-door deposition with the president鈥檚 son and said, 鈥淲e will not provide Hunter Biden with special treatment because of his last name. All Americans must be treated equally under the law.鈥

The top Democrat on the panel, Rep. Jamie Raskin of Maryland, highlighted the hypocrisy that a number of Republicans evaded congressional subpoenas, including Jordan, and yet are trying to hold Hunter Biden in contempt. Raskin claimed Comer has 鈥渂izarrely decided to obstruct his own investigation鈥 because he is refusing to accept Hunter Biden鈥檚 offer to appear for a public hearing.

鈥淭he chairman refused to take 鈥榶es鈥 for an answer from Hunter Biden鈥 Raskin said before getting interrupted by Republicans.

WHAT HAPPENS NEXT?

The pair of markups on Wednesday kick off a lengthy process and underscore that the Republican effort to obtain testimony from the president鈥檚 son will remain difficult. If the contempt resolution passes out of committee, it is referred to the full House for a contempt vote.

If an eventual House floor vote succeeds, the Department of Justice, which is already pursuing two criminal cases against the president鈥檚 son, would have to determine whether to prosecute the president鈥檚 son for evading a congressional subpoena.

Hunter Biden is scheduled to be on the West Coast by Thursday. He has a court appearance in his criminal tax case where he faces nine criminal charges in federal court in Los Angeles.

White House spokesperson for oversight and investigations Ian Sams issued a statement ahead of the committee meetings, dismissing 鈥渂aseless attacks鈥 against the president鈥檚 family members and calling on Republican lawmakers to focus on Congress鈥 other responsibilities.

鈥淚nstead of playing politics, they should do their jobs, fund the government and border security, and focus on solutions that benefit the American people,鈥 Sams stated.

Ahead of the markup, Jordan told CNN he expects the contempt resolution to pass, but did not know when it would come to the floor or how quickly the referral would move through the Justice Department if it got to that point.

鈥淲henever Speaker Johnson wants to put it on the floor, for a floor vote, then it鈥檚 up to Merrick Garland and Mr. Graves,鈥 Jordan told CNN.

With Congress back this week from its winter recess, House Republicans are ramping up their investigations at a busy time on Capitol Hill. The meetings are happening at the same time Wednesday the House Homeland Security Committee is moving forward with its impeachment investigation into DHS Secretary Alejandro Mayorkas.

Sams highlighted that Congress is just days away from a government funding deadline but that House Republicans are instead focusing on their investigations.

鈥淗ouse Republicans are less than ten days from sparking a partial government shutdown that many of their far-right members are rooting for, but instead of working full-time to avoid it, they are wasting time on political stunts,鈥 Sams said in a statement. 鈥淭hese baseless attacks on the President鈥檚 Cabinet and family members will do nothing to help improve Americans鈥 daily lives, strengthen our border security, or improve the economy; all they will do is help extreme House Republicans get booked on Fox and Newsmax to try to distract from their inability to govern.鈥

With the Biden probe moving methodically and a number of Republicans still skeptical about impeaching the president, senior Republicans now believe as the border crisis becomes a defining campaign issue.

鈥淭here鈥檚 a lot of competing impeachments so it鈥檚 tough to tell who is in the lead,鈥 Rep. Tony Gonzales, who serves on the House Homeland Security Committee, told CNN.

鈥淚 will say that I think a lot of the members up here have lost confidence in DHS,鈥 the Texas Republican added.

Jordan said Republicans will 鈥渇ind out鈥 if the House can pursue two impeachments at once, but said he believes 鈥渢here is strong, compelling evidence for both.鈥
