The Washington Post is worried. The lead headline in today’s paper edition reads: “Mueller criticism grows to a clamor — FBI Conspiracy Claim Takes Hold — Driven by activists, GOP lawmakers, Trump tweets.”

Turnabout is fair play. Last year around this time, an honest newspaper could easily have written: “Trump criticism grows to a clamor — Russia Collusion Takes Hold — Driven by activists, Democratic lawmakers, leaks.”

A year ago, an honest newspaper could not have written that the Trump collusion criticism was driven by the FBI. The facts supporting such a headline were not known. Now we have good reason to suspect that the FBI was, in fact, advancing the collusion claim.

The FBI reportedly offered money to Christoper Steele to continue his work on the anti-Trump dossier (in testimony before Congress Rod Rosenstein refused to say whether the FBI paid or offered to pay for the dossier). The FBI may well have used information in the dossier to secure approval of surveillance efforts from the FISA court.

The FBI also helped push the dossier into the public’s consciousness. Its general counsel, James Baker, reportedly told reporter David Corn about the dossier, thus enabling Corn to write about it just before the election. And FBI director Comey briefed president-elect Trump on the dossier, which led to publication of its contents by BuzzFeed.

We also know about the quest of Peter Strzok, a high-level FBI man, for an “insurance policy” against a Trump presidency.

But let’s return to the Washington Post’s story about growing criticism of Mueller. The three distressed Post writers are less than fully open when it comes to informing readers what — other than activists, GOP lawmakers, and Trump tweets — is causing criticism of Mueller to grow to a clamor.

They acknowledge that it has something to do with Strzok’s role as Mueller’s former top investigator. However, they do their best to make Strzok seem innocuous.

The story introduces him by noting that he called Trump an “idiot” and predicted that Hillary Clinton would win the election in a landslide — statements that don’t distinguish him from tens of thousands of government employees and millions of other Americans. They also quote a former colleague of Strzok who says:

To think Pete could not do his job objectively shows no understanding of the organization. We have Democrats, we have Republicans, we have conservatives and liberals. . . . Having personal views doesn’t prevent us from independently following the facts.

The problem with peddling this happy narrative is that it ignores Strzok’s anti-Trump zeal, his obvious desire to impress his mistress, and his damning statement about the need for an “insurance policy” against Trump becoming president. The Post, in fact, never mentions that statement.

The Post also manages to ignore the hyper-partisan nature of Mueller’s staff, even excluding Strzok, whom he reassigned. There is a passing reference to Andrew Weissmann’s gushing note to Sally Yates praising her for her resistance to Trump, but no discussion of the ideologically one-sided composition of Team Mueller — a marked contrast to Ken Starr’s balanced staff.

Even with that diverse staff, Starr was successfully portrayed as spearheading a “vast right-wing conspiracy.” It’s not surprising that as more and more evidence emerges of bias within Mueller’s team, criticism mounts and takes hold.

Mueller himself is a Republican. But he is also a friend of James Comey, another fact the Post ignores. The steady stream of evidence of Comey’s anti-Trump animus and manipulative conduct has contributed to declining faith in Mueller.

And then, there’s the fact that Mueller appears to have come up empty so far on “collusion” by Trump. A prosecutor investigating a president is bound to lose credibility if, after an extended period of time, he neither produces evidence against the president nor exonerates him of the set of crimes that supposedly underlie the investigation.

A prosecutor who cannot credibly be accused of bias — either personal or within his team — buys himself time and patience from the public. Mueller is not that prosecutor.

In sum, the Post’s account of how Mueller lost the “near-universal support” he enjoyed earlier is shallow.

The Post’s story is significant, nonetheless. Clearly, the Post is concerned that, as it states, the growing criticism of Mueller “threatens to shadow his investigation’s eventual findings.”

It does, indeed. A recent Harvard poll found that 54 percent of voters believe that “as the former head of the FBI and a friend of James Comey,” Mueller has a conflict of interest in the proceedings. Meanwhile, only 35 percent believe that evidence of collusion between Trump and Russia has been found.

I’m sure Mueller believes his own press-clippings, but the public no longer does. The press, it seems, is beginning to realize this.
