So why is the identity of this “whistleblower” being kept secret?
It's not, except among the elite, metropoloids, swamp creature and useless fake news media.
America knows his name... and it is Eric Ciaramella.
My theory is the whistleblower is a composite character Democrats created to disseminate their leaks.
While I believe Eric Ciaramella is A whistleblower he's just their a figurehead.
Since he only has his own limited alleged first-hand knowledge he doesn't know all the things every other leaker have given Democrats. Democrats can't risk him testifying because he would fall apart during questioning.
