I disagree in terms of Occam’s Razor, actually, since that makes a pretty massive assumption that people in the white house are Russian agents.
I think it’s more likely that Turnip&Co are absolutely unwilling to admit any sort of error/oversight (see: Sean Spicer’s bullshit, Obama wire-tapping claims, etc etc). Their I’m-always-right machismo prevents them from admitting that they chose the wrong person for the position, and they’re willing to do anything to protect that image. Add in a healthy dose of short-term thinking, our twit(terer)-in-chief’s forte, and you get all the face-saving nonsense going on now.
Not that any of that suggests that there wasn’t/isn’t the stain of Russian interference all over the current administration. I think there’s more than enough circumstantial evidence to make that a VERY likely possibility.
