President Trump's use of Twitter to threaten Iran brought renewed calls for CEO Jack Dorsey to take action to limit the president's use of the platform. However, Twitter maintains none of the president's messages violate the company's policies.
The bigger picture: Twitter has said that, in general, it will leave political leaders' tweets up even if they violate the terms of service that apply to other users. Last year it announced a policy that would see the company append a warning to tweets deemed to violate its rules. But, it has yet to apply that policy to Trump or anyone else.
