Two whistleblowers who alleged the Justice Department politically interfered with an investigation into President Biden’s youngest son, Hunter, will testify before Congress at 1 p.m. Wednesday, including "Whistleblower X," a 13-year special agent of the IRS whose identity will be revealed for the first time during the hearing, and former investigation supervisor Greg Shapley.

According to an opening statement released ahead of the hearing, the unidentified official intends to describe himself as a "whistleblower compelled to disclose the truth" and to shed light on "the shadow that looms over our federal legal system."

"I have witnessed the corrosion of ethical standards and the abuse of power that threaten our nation. It is within this context that I have chosen to shed light on these actions and expose those responsible. I recognize that while I was present at the start of this investigation and was closely involved with the investigation for roughly five years — that I am just a part of the story," the opening statement continued. "My aim is to address systemic problems that have allowed misconduct to flourish. It is not a call for blame but a call for accountability and reform."
