The corruption within the FBI and Department of Justice has reached cosmic proportions. And because of it taxpayers must demand the politically driven Russian collusion probe be shuttered immediately.

It’s become evidently clear it’s a sham investigation reeking of corruption at every turn.

How much longer must this charade, on the backs of taxpayers, go on?

First former FBI Director James Comey, an anti-Trump hack who has admitted to leaking sensitive memos to the press, kickstarted the alleged Russian collusion investigation based on a discredited dossier commissioned and paid for by the Clinton campaign and Democratic National Committee. If that’s not illegitimate enough, U.S. intelligence agencies then used the debunked dossier compiled by Russian informants, via the slimy opposition research firm Fusion GPS, to obtain FISA warrants to spy on candidate Donald Trump and his campaign associates — to lay traps for them.

In order to derail the Trump administration and construct a basis for impeachment.

This is what meddling in an election looks like — only it was done domestically, by the Obama administration and our own Justice Department.

Let that sink in.

Now we learn that one of Bob Mueller’s top investigators, Peter Strzok, the deputy head of FBI counterintelligence, was secretly removed from the Russian investigation last summer — unbeknownst to Congress — for sending anti-Trump and pro-Hillary Clinton texts to a colleague — revealing major political bias.

Here’s why it matters: Strzok, a compromised agent with a political agenda, had his dirty fingerprints on both the Clinton email investigation and the ongoing Russian probe. For starters, he was instrumental in exonerating Hillary Clinton and her associates over the mishandling of classified emails despite troves of damning evidence. Strzok was also the agent who interviewed Hillary Clinton last summer without recording it or putting her under oath, thereby shielding her from a process prosecution or perjury trap — not afforded to others — namely Trump associates, including Michael Flynn, who is now facing perjury charges.

Hardly “Justice for All.”

What has become apparent is the FBI — America’s most powerful instrument of justice — is dispensing “Justice for Some,” based on how you vote. In other words, they’ve become a weaponized arm of the Democratic Party.

Add to it, it was Strzok we’ve now learned who made the recommendation to Comey that Hillary Clinton not be prosecuted despite grossly mishandling classified information, destroying evidence under Congressional subpoena and wiping servers — all of which jeopardized America’s national security.

Leading President Trump to tweet yesterday, “Report: “ANTI-TRUMP FBI AGENT LED CLINTON EMAIL PROBE.” Now it all starts to make sense!”

Indeed it does. The Russian investigations — costing taxpayers millions — have been a gross miscarriage of justice.

Time to shut it all down.
