In a development that intensifies the impeachment inquiry into President Joe Biden and his family, House Republicans are set to issue subpoenas to Hunter Biden and James Biden as the special counsel overseeing the investigation, David Weiss, prepares to testify before the House Judiciary Committee on Tuesday. This marks the first time a special counsel will respond to congressional investigators' questions amidst an ongoing investigation.

James Comer, Chairman of the Oversight Committee, has indicated that his panel is ready to send out a series of subpoenas as part of the impeachment inquiry focused on the business dealings of the Biden family. Sources connected to the investigation have disclosed to NBC News that among those expected to receive subpoenas as early as this week are Hunter Biden and President Biden's brother, James Biden.

Representatives for James and Hunter Biden have yet to comment on the pending subpoenas.

David Weiss, the U.S. attorney from Delaware who heads the Justice Department's investigation into Hunter Biden, voluntarily agreed to testify before Congress to address inconsistencies between his public statements and the public testimony of two IRS investigators. These investigators claimed that Weiss had stated he lacked the ultimate authority to bring charges against the president's son.

Weiss's unprecedented testimony follows the rejection of a plea agreement with Hunter Biden by the judge presiding over the case. Despite leading an indictment of Hunter Biden on gun charges, Weiss requested and was granted special counsel status. This move allows him to appear before Congress, even during an ongoing investigation.

Last month, Hunter Biden pleaded not guilty to three firearms charges and announced his intention to have the federal indictment dismissed.

House Republicans have accused the Justice Department of showing preferential treatment to the president's son. Joseph Ziegler and Gary Shapley, two IRS investigators, testified under oath that Weiss, a Trump appointee, faced obstacles from other U.S. attorneys and senior officials in the Department of Justice that prevented him from pursuing the investigation. Shapley also presented handwritten notes from a meeting, indicating that Weiss had stated he was not the ultimate decision-maker on whether charges would be filed.

Weiss has written multiple letters to Congress refuting these claims and is expected to provide specific details about his level of authority in his testimony on Tuesday.

While Republicans are eager to explore the Justice Department's probe into Hunter Biden, Weiss has clarified that he will only address any disparities concerning his authority to bring charges. He will not reveal specific details about the ongoing investigation, according to Hornbuckle, a spokesperson for Weiss.

Following this closed-door interview, it is unlikely that Weiss will appear before the panel again until his investigation concludes. He will be responsible for submitting a final report and potentially filing additional charges. There remains the possibility of additional indictments for Hunter Biden, particularly regarding the tax charges that were at the center of the failed plea agreement.

Simultaneously, the Judiciary, Oversight, and Ways and Means committees are continuing their joint impeachment inquiry.

Rep. Comer, in a recent Fox News interview, indicated that the committee is prepared to issue a significant number of subpoenas and request interviews with members associated with the Biden family. He projected the issuance of approximately two dozen subpoenas in the near future.

GOP members of the Oversight Committee released various reports derived from subpoenas of Biden family bank records. These reports show a series of transactions between Joe Biden and James Biden, seemingly portraying short-term, interest-free loans from the president to his brother. The committee has made public two checks written by James to Joe Biden, totaling $240,000, marked as "loan repayments" in the subject line. These transactions took place after Joe Biden left the vice president's office but before his election as president in 2020.

Comer has accused the Biden family of engaging in "shady business practices." Nonetheless, concrete evidence of wrongdoing or influence peddling by President Biden himself has yet to be presented using these specific transactions.

Speaker Mike Johnson, who recently assumed the position and has expressed concerns about the Biden family's business practices, has adopted a cautious approach towards the impeachment inquiry. He has stated that he does not want to pre-determine its outcome and prefers to allow the investigation to proceed in adherence to due process and the law.

"We have to follow due process and we have to follow the law, and that means following our obligation to the Constitution and doing appropriate investigations in the right way and at the right pace," Johnson emphasized during a news conference.

As the investigation unfolds, all eyes are on the House Judiciary Committee hearing with David Weiss on Tuesday, which may shed light on the extent of the ongoing probe into the actions of the Biden family.
