Welcome to the Twilight Zone: Under immunity deals given to two key Hillary Clinton aides in the e-mail probe, the FBI wound up destroying evidence.

Once they were done searching two laptops used to store Clinton’s e-mails, the agents had to destroy them. They also had to limit their search to include nothing after January 2015 — that is, before news broke of the whole home-brewed-server business.

Meaning the FBI investigation had that much less chance of stumbling across fresh proof of obstruction of justice.

All this to get Cheryl Mills and Heather Samuelson to hand over laptops the Justice Department could’ve gotten via subpoena — with no need for strings.

Kudos to Fox News for breaking this latest rancid story, thanks to the reporters’ sources on the House Judiciary Committee.

Less than a month after reaching the immunity deals, FBI chief Jim Comey publicly declared Clinton shouldn’t be prosecuted, because she never outright intended to break the law. (And never mind that “intent” isn’t an issue in the law in question.)

All this is on top of the Justice Department’s absurdly gentle treatment of Mills. Notably, it let her refuse to answer questions about Clinton’s use of the private server even after it learned she’d lied when she found out about it.

As Judiciary Chairman Bob Goodlatte (R-Va.) notes, the latest revelations “raise more questions than answers” — “like many things about this case.”

Yet the big answer is now obvious: President Obama publicly declared Clinton to be in the clear before the probe even began, his Justice Department made sure that’s what the “investigation” would find — and Comey let the FBI get roped into playing the beard.
