Donald Trump’s favorite vehicle to relay messages is no doubt Twitter, but many people argue he is violating the rules of the social media platform. His tweets this week about “civil war” and threats to uncover the whistleblower’s identity are especially of concern. Senator Kamala Harris (D-CA) is the most prominent person to ask Twitter to take action. The presidential candidate told CNN’s, Anderson Cooper:

“I, frankly, think that based on this and all we’ve seen him do before, including attacking members of congress, that he, frankly, should be — his twitter account should be suspended. I think there’s plenty of now evidence to suggest that he is irresponsible with his words in a way that could result in harm to other people. And so the privilege of using those words in that way should probably be taken from him.”

“So what we see continuously, including in the last 24 hours… Donald Trump using his words in a way that could subject someone to harm. And if he’s not going to exercise self-restraint, then, perhaps, there should be other mechanisms in place to make sure that his words do not, in fact, harm anyone. And that’s my point. What we want to make sure is that his words do not actually result in harm to anyone.”

We looked at Twitter’s official rules and found a couple that Trump could be violating:

• You may not engage in the targeted harassment of someone, or incite other people to do so. 
• You may not use our service for any unlawful purpose or in furtherance of illegal activities. 

We reached out to Twitter for a response, but they declined to comment.
