Trump's itchy Twitter thumbs have redefined politics
In the year since his election, Donald Trump has used Twitter as an official White House channel for everything from policies and praise to bullying and brinksmanship.
"Regardless of whether you support or oppose Trump, he is a dramatic demonstration of the platform's impact in that space," said Adam Sharp, Twitter's former head of news, government and elections. "While I do wish he would use it as a force for good, I think he's motivated very much by the mainstream media attention he gets. On the other hand, I'm not so sure the media would cover him as intensely if he was much more tame."
