Trump credits social media for win

President-elect Donald Trump credited his provocative use of Twitter and other social media with helping him win the US elections, saying it gave him a way of "fighting back." "The fact that I have such power in terms of numbers with Facebook, Twitter, Instagram, et cetera, I think it helped me win all of these races where they're spending much more money than I spent. And I won," he said in a CBS interview released late Saturday.
