In other words, Nunes, his committee cohorts and other House members are engaged in a cover-up to deflect attention away from themselves. Clearly, it was an idiot move as now anyone even remotely associated with the Trump-Russia team may now appear under the FBI's gaze. In short, this deflection now casts a suspicious reflection upon any House member who attempts to defend Trumpski.
The message, then, is loud and clear to all House members. Time to clam up and seek shelter from the coming storm, and hope like hell the FBI doesn't puncture the bubble.
