The Internal Revenue Service (IRS) agent who alleges the criminal investigation into Hunter Biden has been corrupted by lies and politics is being pulled from the inquiry in a possible act of retaliation, lawyers for the IRS official say.

These attorneys informed Congress on Monday that their client, identified as a criminal supervisory special agent, was told “that he and his entire investigative team are being removed from the ongoing and sensitive investigation of the high-profile, controversial subject about which our client sought to make whistleblower disclosures to Congress,” according to The New York Post.

Mark Lytle and Tristan Leavitt, the lawyers for the IRS agent, said their client was “informed the change was at the request of the Department of Justice.” They also said the “move is clearly retaliatory and may also constitute obstruction of a congressional inquiry.”

The Daily Wire reached out to the IRS as well as the Department of Justice (DOJ) seeking comment on the new claim.

FBI and IRS investigators have reportedly been looking into Hunter Biden’s business dealings, tax affairs, and more for years now. After Biden’s lawyers met with Department of Justice officials late last month, sources told The Washington Post that potential charges for tax- and gun-related crimes may soon follow from Delaware’s U.S. Attorney David Weiss.

Hunter Biden has said he expects to be cleared of wrongdoing, and his father, President Joe Biden, told MSNBC this month that his son has “done nothing wrong.”

The IRS supervisory agent, who has not been publicly identified, reached out to top lawmakers last month seeking to make protected whistleblower disclosures to Congress about a high-profile investigation which has since been identified as the Hunter Biden probe. Lawyers for the IRS agent then met with congressional investigators, laying the groundwork for what could be a formal disclosure involving sensitive tax information in the near future, CNN reported this month.

Lytle has revealed that his client already made disclosures to multiple inspectors general, including “examples of preferential treatment and politics improperly infecting decisions,” a “failure to mitigate clear conflicts of interest in the ultimate disposition of the case,” and claims that “contradict sworn testimony to Congress by a senior political appointee.” Lytle told CBS News that his client has emails and other communications to back up his disclosures.

The senior official referenced by Lytle in his letter to Congress has been identified as Attorney General Merrick Garland, who spoke briefly about the inquiry during congressional testimony in March. “I pledged not to interfere with that investigation and I have carried through on my pledge,” Garland testified to the Senate Judiciary Committee.

Pressed about the IRS whistleblower and his testimony during a recent news conference, Garland said his statement under oath remains true. “Yes, it’s still the case,” Garland said. “I stand by my testimony and I refer you to the U.S. attorney for the district of Delaware, who is in charge of this case and capable of making any decisions that he feels are appropriate.”

Hunter Biden’s attorney, Chris Clark, told news outlets the IRS official “appears” to have committed a crime. “It is a felony for an IRS agent to improperly disclose information about an ongoing tax investigation,” Clark said in a statement reported by NBC News.

Lytle told Fox News the statement was “unfortunate” but stressed that his client is not backing down. “Attacks like this are kind of what he was worried about, but he wants to come forward and tell the truth,” he said.

In their letter to lawmakers on Monday, the IRS agent’s lawyers highlighted sections of U.S. Code outlining rules against blocking or retaliating against officials seeking to make whistleblower disclosures to Congress and noted that IRS Commissioner Daniel Werfel vowed to the House Committee on Ways and Means last month that there would be “no retaliation” against whistleblowers.

“We respectfully request that you give this matter your prompt attention,” the IRS agent’s lawyers wrote. “Removing the experienced investigators who have worked this case for years and are now the subject-matter experts is exactly the sort of issue our client intended to blow the whistle on to begin with.”

The attorney for 24-year-old former Marine Daniel Penny said during an interview on Monday that the Jordan Neely had started “swinging his arms at passengers” on a subway in New York City when his client stepped in to protect the passengers.

Penny placed Neely, a homeless man with over 40 arrests and a history of mental health issues, in a chokehold after Neely embarked on an aggressive rant and began screaming that he did not care if he went to jail.

Appearing in his first interview for the case, attorney Steve Raiser was asked by Fox News host Judge Jeanine Pirro what Penny’s mindset was when he put Neely into a chokehold.

“He was fearful for the safety of those passengers,” Raiser said. “So when he acted, his mindset was to keep his fellow passengers safe from attack. Neely entering the train and acting in a very violent manner, both physically and with words. He would say things to the effect that, you know, I need certain things, I need food, I need this or that. And if I don’t get it, I don’t care if I go to prison for the rest of my life. And the passengers actually have said that they interpreted that to mean, well, when would you go to prison for the rest of your life if you kill somebody? So everybody got the message.”

Raiser said that the situation rapidly escalated to the point where Neely was “swinging his arms at passengers, throwing his jacket down, [and] making threats” toward the passengers.

Raiser says that they were told that a grand jury was going to be impaneled to go through “a very deliberate process” to determine if charges should be brought in the case and that they “got a call one night before Danny was asked to surrender and said he’s got to surrender to the police department tomorrow so at that point we were like, what do you mean tomorrow, this was going to be a long process suddenly it’s tomorrow.”

Raiser dismissed critics who claim that Penny only acted because Neely was black.

“None of that is based on the facts,” he said. “As to race, it’s simply not the motivation for Danny. He is the one that put himself in danger, to save who? All the people on that train. Black people, brown people, white people, it didn’t matter to Danny. Danny put his life at risk to save all those people. It has nothing to do with race.”
