IRS whistleblower: 'Independent attorney' needed to fully execute Hunter Biden investigation

IRS Agent Joseph Ziegler joins'Special Report' to respond to critiques of hearing, letters from Del. prosecutor. The IRS special agent-turned-whistleblower formerly known as "Mr. X." spoke out to Fox News on Friday following an at-times contentious congressional hearing earlier this week. Joseph Ziegler, who came forward to Congress along with his colleague, Gary Shapley, said his team uncovered "a ton of evidence" that proved Hunter Biden allegedly willfully evaded or fraudulently filed his taxes, which set him apart from a typical IRS investigatory subject that would be faced with civil fines. Ziegler also told "Special Report" the ultimate reason he came forward as a whistleblower was that he saw many instances where federal officials were not following proper procedures.
