US President Donald Trump defended his regular use of social media, especially Twitter, and said he may not have won the White House without it.

In an interview airing on Sunday on "Fox Business Network," Mr Trump says he can bypass what he labels unfair media coverage by speaking directly.

"Tweeting is like a typewriter -- when I put it out, you put it immediately on your show," he said, according to a transcript released by the network. "I doubt I would be here if weren’t for social media, to be honest with you."

Mr Trump called his social media accounts on Facebook Inc , Twitter Inc and Instagram "a tremendous platform."

"When somebody, says something about me, I am able to go bing, bing, bing and I take care of it. The other way, I would never be get the word out," he said, according to the transcript.
