A small but important distinction, one that is often overlooked by the media, is Judge Rudolph Contreras didn't recuse himself. He was recused.The judge recused himself after the guilty plea from Flynn. Interesting
The chief judge of the District Court is the one responsible for assigning cases to the District judges (to prevent judge shopping, equally distribute case load, among other reasons),and it was this judge who recused Contreras from the Flynn case. And it's almost certainly because the chief judge was made aware by IG David Horowitz of the Strzok-Page text messages that showed the relationship.
Remembering that Strzok interviewed Flynn, the text messages that talked of orchestrating a cocktail party as "cover" for meeting with Contreras to talk about Flynn is known in legal circles as a smoking gun.
Contreras allowed a guilty plea to be entered without requiring any and all exculpatory evidence in Mueller's possession to be presented to the court. That's problematic enough. But I have a feeling that Horowitz said to the chief judge something along the lines of, "If these text messages ever become public, and I expect they will, then Contreras will be guilty of corruption and obstruction."
And just like that, Contreras was abruptly recused from the case and another judge was assigned.
