Rudy Giuliani, the cyber security adviser of Trump doesn't understand Internet
Rudy Giuliani is the former mayor of New York and the current cyber-security adviser of president Trump. However, Giuliani does not really understand the internet or Twitter where the president is quite active. Giulani tweeted about the president and G-20 and forgot to add space after a period. As a result, a hyperlink was created and redirected to a Trump criticizing page. Alas, the tweet came from a cyber-security adviser.
