Twitter clarified when it will enforce rules against "world leaders." Which is Twitter's way of relaying what Donald Trump can do on the platform. The upshot: Unless Trump explicitly violates Twitter's rules, leaving no room for interpretation, the company will do nothing.

"We focus on the language of reported Tweets," Twitter said in a blog post Tuesday, "and do not attempt to determine all potential interpretations of the content or its intent."

Twitter's blog post comes in the wake of a series of controversial tweets from Trump that drew condemnation from Sen. Kamala Harris, a Democrat representing California and running for the party's nomination for president, who called for Twitter to suspend him.

"Trump's tweets about the whistleblower represent a clear intent to harass, intimidate, or silence their voice," Harris wrote in an open letter to Twitter CEO Jack Dorsey. "His blatant threats put people at risk — and our democracy in danger. His account must be suspended."
