Trump says he ‘knows a lot about hacking’ and doesn't trust computers

US president-elect Donald Trump says that “no computer is safe” when it comes to keeping information private, expressing new scepticism about the security of online communications his administration is likely to use for everything from day-to-day planning to international relations.

Trump rarely uses email or computers despite his frequent tweeting.

“You know, if you have something really important, write it out and have it delivered by courier, the old-fashioned way. Because I’ll tell you what: No computer is safe,” Trump told reporters during his annual New Year’s Eve bash. “I don’t care what they say.”

Trump, who has said that he plans to meet with intelligence officials this week to learn more about the allegations, said he wants US officials “to be sure because it’s a pretty serious charge”. He pointed to intelligence failures over the existence of weapons of mass destruction in Iraq before the US invasion, and declared himself an expert in the area.
