Washington - US president-elect Donald Trump says the CIA's conclusion that Russia interfered in the presidential election is "ridiculous" and being used by Democrats as "just another excuse" for his defeat of Hillary Clinton.He told Fox News Sunday that he didn't necessarily oppose President Barack Obama's order for a review of campaign-season cyberattacks. But he added that in any such effort "you should not just say 'Russia'. You should say other countries also, and maybe other individuals."The Obama administration has said the review is not just about Russia or the election. The White House says the report will look at other election-year incidents, including 2008 and 2012 cyberattacks linked to Chinese hackers.Trump has long said the culprit could be China or just a random hacker sitting on a couch. The CIA has concluded with "high confidence" that Russia sought to influence the US election on behalf of the Republican.
