Hunter Biden turns on Joe as he sues his dad for releasing tax returns

It also claimed his personal tax details were shared during congressional hearings and media interviews in an “assault” on his right to confidentiality.

The President’s son is seeking $1,000 (around £800) for each disclosure and associated legal fees.

Agents Greg Shapley and Joe Ziegler, who were acting as whistleblowers, accused the Department of Justice of “slow-walking” the investigation in testimony before Congress.

The Department of Justice has rejected allegations of political interference in the case.

Hunter’s lawsuit suggests the agents “targeted and sought to embarrass” him and the tax agency failed to protect his private records.

It also argued whistleblower protections do not include sharing personal tax details and other confidential information.

However, Hunter’s lawsuit against the IRS comes just days after he was indicted over a potential gun charge.

A plea deal collapsed ahead of the indictment which would have seen the 53-year-old plead guilty to minor tax offences and avoid charges of possessing a firearm for 11 days while using drugs.

He faces a possible trial next year on three federal gun charges filed last week.

Prosecutors also allege Hunter, who could still face prosecution for alleged tax crimes, earned taxable income of at least $1.5million (£1.21million) in each of the calendar years 2017 and 2018.

However, the Commander-in-Chief’s son did not pay income tax in those years.

Republicans on the Capitol have also renewed efforts to launch a formal impeachment inquiry against Hunter’s father Joe.

Speaker Kevin McCarthy announced he was launching an impeachment inquiry after alleging a “culture of corruption” involving the Biden family.

Democrats claim the effort is “extremist” but McCarthy claims the move is not political and instead aimed at getting “answers”.

A five-year probe into Hunter has not produced accusations of financial crimes beyond failing to pay taxes.
