What Trump should do is to declassify something (any investigations into Hillary Clinton, Hunter Biden, Christopher Steele dossier). Then give the information to Donald Trump Jr so he could give it to Sean Hannity or Rush Limbaugh to read on the radio or on a television show.
I agree threats mean nothing anymore, we are long past that.
After seeing these huge tech companies blacklist and delete all kinds of things, I don’t think Trump can hurt them with a dump of declassified damning date. they will just make it disappear and the media wont cover it.
