Twitter is creating a warning label to flag and suppress political tweets that break the platform's rules on acceptable speech. It's a bold step for the company, which has come under sharp criticism for its handling of tweets by major political figures including President Trump. The company will not delete the offensive, bullying or hateful tweets of politicians. But, it announced in a blog post Thursday, it will begin marking them up. When a politician's tweet breaks the rules, it will get hidden under a warning label that says: "The Twitter Rules about abusive behavior apply to this Tweet. However, Twitter has determined it may be in the public's interest for the Tweet to remain available."
