U.S. President Donald Trump, who has garnered a large following on social media with rambunctious postings, said he sometimes tweets from bed, though he occasionally allows others to post his words.

Trump frequently uses Twitter to announce policy, assail his adversaries and to tangle with countries, including North Korea, over world affairs. The @realDonaldTrump account had 47.2 million users as of Sunday.

In an interview with Britain's ITV channel, he appeared to appreciate the wide impact of his postings in Twitter and said that he needed social media to communicate with voters in the era of what he termed fake news.
