A second IRS whistleblower has emerged to corroborate claims of political corruption in the Hunter Biden tax investigation. 

The whistleblower complained the Department of Justice has been "acting inappropriately" in the case, which he handled for five years before he was abruptly dismissed last week, the New York Post reported.

The whistleblower is a subordinate of the IRS supervisor who originally blew the whistle on political interference from the Department of Justice in April. Both agents were abruptly dismissed last week along with the entire investigative team.

Hunter Biden whistleblower

The new information was shared by lawyers for the first whistleblower, who blasted a "baseless and absurd" warning his subordinate received after he complained directly to IRS leaders through e-mail.

The agent was reprimanded for breaking the "chain of command" and told he may have violated the law, in "an apparent attempt to intimidate into silence anyone who might raise similar concerns," lawyers for the first whistleblower alleged in a letter to IRS director Daniel Werfel.

The case agent had written that he was "removed this week from a highly sensitive case....after nearly 5 years of work" and that he and his supervisor were "isolated" for raising issues with the case to senior leaders.

“For the last couple years, my [supervisor] and I have tried to gain the attention of our senior leadership about certain issues prevalent regarding the investigation. I have asked for countless … meetings with our chief and deputy chief, often to be left out on an island and not heard from,” the agent wrote.

Retaliation

The original whistleblower also included a letter to the Office of Special Counsel alleging a series of retaliatory actions prior to the dismissal of his investigative team.

Among other steps, the agent said he was passed over for a promotion and that his team was excluded from phone calls since he began raising concerns about the case in the summer of 2020.

Hunter Biden has been under investigation since 2018 by U.S. attorney David Weiss, a Trump appointee.

The IRS supervisor blew the whistle last month, saying he had witnessed political tampering and alluding to perjury from attorney general Merrick Garland, who has pledged to protect the investigation's independence.

The supervisor will testify privately to the House Ways and Means Committee on Friday. It was not known whether or when the subordinate would testify, but evidence is mounting that may not be ignored much longer, no matter how many in the media and White House try to make it go away.
