David Harsanyi of the Federalist analyzes recent revelations involving federal law enforcement agents.

Two veteran IRS agents with impeccable records have now testified under oath that federal officials not only slow-walked the Hunter Biden probe but nixed efforts to investigate Joe’s role in the family business. And though legacy media are conveniently apathetic about the developments, they seem somewhat newsworthy to me.

On Wednesday, we learned the identity of “Whistleblower X.” Joseph Ziegler, a self-proclaimed Democrat who worked at the agency since 2010, told the House Oversight Committee that he handled 95 percent of the evidence in the Hunter tax investigation. Ziegler testified that throughout the five-year investigation, he was “handcuffed,” “hamstrung,” “marginalized,” and ultimately stopped from moving forward in the manner he would for any other scofflaw.

Ziegler wrote a 99-page memo laying out the case for felony charges, wholly consistent with the IRS guidelines governing charging in tax evasion cases. He maintains that every investigator and prosecutor on the case agreed felonies were in order — all of which should be easy enough to find out.

Sure, it’s fun to talk about salacious parts of the Hunter case, but the far bigger concern should be finding out why companies operating in authoritarian nations sent Biden $17 million. It would be a fair question even if there had been no criminal investigation.

Now, I’m not saying the feds were covering up proof of Joe Biden’s illegality — though circumstantial evidence and common sense say the family business couldn’t function without his participation. I’m saying it’s increasingly clear the Justice Department didn’t want to find out if there was any evidence. No one wanted a replay of the Hillary-illegal server scandal. And that’s how Hunter got his sweet deal.

“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 approvals. We can’t ask those questions,’” Ziegler told CBS News. “And I mean, it created an environment that was very hard to deal with.”
