Rudy Giuliani, who most people know as the former mayor of New York City and a failed presidential candidate, is also President Trump’s attorney in the Russia investigation. A lot of people know that too. But what they may not know is that Giuliani is also an informal adviser to Trump on cybersecurity.

Keep that in mind as we travel back to Friday, when Giuliani tweeted some complaints about Special Counsel Robert Mueller. The context isn’t important. All you need to know is that in his haste, or his attempt to emulate Trump, Giuliani included several typos in the tweet, including the omission of a space at the start of a sentence that started with the word “in.” The placement of a period and no spaces between “G-20” and “in” resulted in an inadvertent hyperlink showing up in Giuliani’s tweet.

Mueller filed an indictment just as the President left for https://t.co/8ZNrQ6X29a July he indicted the Russians who will never come here just before he left for Helsinki.Either could have been done earlier or later. Out of control!Supervision please? — Rudy Giuliani (@RudyGiuliani) November 30, 2018

A clever scamp quickly snatched up the URL G-20.in and set up this page:

That’s pretty embarrassing by itself, but Giuliani made the error even worse Tuesday night when he blamed the hyperlink in Friday’s tweet on Twitter, which he accused of allowing “someone to invade my text.”

Twitter allowed someone to invade my text with a disgusting anti-President message. The same thing-period no space-occurred later and it didn’t happen. Don’t tell me they are not committed cardcarrying anti-Trumpers. Time Magazine also may fit that description. FAIRNESS PLEASE — Rudy Giuliani (@RudyGiuliani) December 5, 2018

Once again, Giuliani is Trump’s special adviser on cybersecurity and he doesn’t understand that the link was generated automatically. Or that the reason Helsinki.Either didn’t also turn into a link is that .either is not a valid domain name. But the most damning part of this story? Both tweets are (at least at the time of this posting) still up.
