The Dems are afraid the Nunes will let the cat out of the bag that Trump and his staff were “Wiretapped/Surveilled”. When the democrats are exposed on that and then it is concluded that nobody in the Trump Administration colluded with the Russians they will be sitting there with egg on their faces and no more arguments to excuse their electoral failures. But then again, that will just be an opportunity to invent somethings else. Stay tuned!
It won’t be egg on their faces, it will be a scornful reaction to having an arrest warrant slapped on across their face (not on the wrist).
