IRS Whistleblower Joseph Ziegler: "Roadblock After Roadblock Was Put In Front Of Me" During Biden Probe

IRS special agent Joseph Ziegler, previously referred to as "Agent X," told CBS News reporter Catherine Herridge that he "felt handcuffed" during a five-year investigation into the president's son's international business deals, in an interview airing in full Wednesday night after his testimony this afternoon at the House Oversight Committee.

Herridge asked the key question: "Did you uncover evidence that President Biden financially benefited from his son's deals?"

"I don't feel comfortable answering that question... Any time we potentially wanted to go down the road of asking questions related to the president, it was, 'That's gonna take too much h approvals, we can't ask those questions.' And I mean, it created an environment that was very hard to deal with," Ziegler told Herridge.
