"Made McCabe look like a choirboy"
In other words, McCabe has been singing his little heart out! Lolololololol!
The problem for the cabal is that they can't get used to the idea that their usual secure comms are compromised (she wasn't meant to lose) and all their plans are now an open book to POTUS who hears and sees all and knows exactly what they're planning. Hence their desperate, last-ditch attempts to communicate (rather obviously) via Twatter.
Indeedy!
