US President-elect Donald Trump says that "no computer is safe" when it comes to keeping information private, expressing new skepticism 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 has repeatedly cast aside allegations by US intelligence agencies that Russia tried to influence the presidential election through hacking. President Barack Obama earlier this week ordered sanctions on Russian spy agencies, closed two Russian compounds and expelled 35 diplomats the US said were really spies. The Russian government has denied the allegations. Trump, who has said that he plans to meet with intelligence officials next to 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. "I know a lot about hacking. And hacking is a very hard thing to prove, so it could be somebody else," he said. He added, cryptically, that he also knows "things that other people don't know. And so they cannot be sure of the situation." Trump made the comments during his annual New Year's Eve bash at his Mar-a-Lago club. Hundreds of guests gathered in the club's grand ballroom, including action star Sylvester Stallone and romance novel model Fabio. Reporters were invited to watch as guests arrived. — AP
