If Warren was "silenced" then why am I still seeing and hearing from her every day, everywhere else? 
Again, the hyperbolic hysteria of the Left is at play, aided by a compliant MSM, spouting what they themselves like to call “fake news”.  If they want to see a “shut down” of free speech, then visit Berkeley or the US universities and colleges in when a conservative speaker is invited and may dare to show his or her face with a view to debate ideas. The Left and the Democrats have no understanding that in electing Trump, Middle America has “tuned” them out, along with their puerile and constant psychological projection about the evil motives of conservatives.
