House Republicans requested testimonies from more than a dozen officials from the Justice Department, the FBI, and other government agencies concerning the federal tax investigation into President Joe Biden’s son, Hunter Biden.

The Republican committee leaders in the House of Representatives argue that such testimonies are critical, especially in light of allegations raised by whistleblowers from the Internal Revenue Service. These whistleblowers claim that the DOJ had potentially intervened in the tax probe in an effort to safeguard Hunter Biden.

US Attorney General Merrick Garland, however, countered these whistleblower accusations last week. He stated that the leading prosecutor, appointed by former Republican President Donald Trump, had been granted full autonomy in terms of making decisions about charges. Garland firmly dismissed the allegation that the Justice Department might have intervened inappropriately in the investigation.

Long-standing efforts by the House Republicans to investigate President Biden, his administration, and his family have consistently been at the top of their agenda. Such appeals for action have been amplified since Trump was indicted on criminal charges related to mishandling classified government documents. Speaker of the House, Republican Kevin McCarthy, cautioned earlier this week that impeachment might be a possible outcome for Garland due to the whistleblower allegations.

The Justice Department, acknowledging receipt of the letter, declined to comment further. According to court documents filed last week, Hunter Biden has agreed to plead guilty to two misdemeanor charges related to willful failure to pay income taxes. This agreement could potentially prevent a conviction on a firearms-related charge.
