The social media platform sought to clarify its rules for politicians Tuesday after coming under pressure from Senator Kamala Harris, a Democratic presidential candidate, to suspend President Donald Trump's account.
"We want to make it clear today that the accounts of world leaders are not entirely over our policies," Twitter said in a blog post, adding that part of its mission is to allow people to "directly engage their leaders."
According to these rules, tweets from world leaders that violate the platform's policy will remain online if they have "clear public interest value." In some cases, Twitter will place the tweet behind a note that provides context.
It said that "direct interactions with other public figures, comments on current political issues or foreign policy sabotaging on economic or military issues are generally not in violation of" the rules.
Still, the company has drawn some red lines that also apply to world leaders. It will take action if tweets promote terrorism, include private information or intimate images, participate in child sexual exploitation or promote self-harm.
The company will also act when direct threats of violence are made against an individual. It said, however, that "context is important" and that interactions between public figures are unlikely to qualify.
"We realize we work in an increasingly complex and polarized political culture, "said the blog post. "These are constantly evolving challenges and we will keep our policies and practices under advisement."
Harris, a former California attorney, has sought to make Trump's Twitter account a campaign issue.
