Rudy Giuliani, who was named President Trump’s cybersecurity advisor last year, demonstrated on Tuesday that he does not understand how Twitter works...or hyperlinks...or domain registration.

Giuliani tweeted that Twitter had allowed someone to “invade” a tweet he sent on November 30, because that tweet linked to a website with the words “Donald J. Trump is a traitor to our country.”
