Shutting down twitter puts a major damper on Trump communicating directly with the voters.
This is the work of Anonymous with the intent of proving that shutting down Assange won’t stop anything. Here in Kentucky everything is still working fine, including Twitter, where I am getting the info on Anonymous. Appears that the DDOS continues, though, for the east coast and now the west coast is getting hit. Also outages in Texas.
Put nothing past the globalist fascists.
