Chuck Ross of the Daily Caller sifts through the latest evidence that special counsel Robert Mueller’s legal team has an ax to grind in its pursuit of charges against President Trump.

For nearly four months, Special Counsel Robert Mueller’s office, the Justice Department and the FBI have kept secret the fact that the FBI agent who oversaw the Russia investigation exchanged anti-Trump and pro-Hillary Clinton text messages with an FBI attorney who was also his mistress.

Those messages, the existence of which were revealed in bombshell reports published over the weekend, highlight a pattern of the Mueller team.

Many of Mueller’s prosecutors — it has been extensively reported — have made campaign contributions to Clinton and other Democratic political candidates. And a review by The Daily Caller shows that Mueller lawyers involved in the cases against four Trump associates are Democratic donors.

But Peter Strzok’s text messages — which he exchanged with Jill Page, an FBI lawyer who worked briefly on the Russia investigation — are perhaps the most significant evidence of anti-Trump bias uncovered so far on the Mueller team.

The discovery could also undermine the integrity of Mueller’s expansive investigation. That’s because Strzok is the FBI agent picked in July 2016 to supervise the then-fledgling investigation into possible collusion between the Trump campaign and Russian government.
