After 56-year-old Cesar Sayoc, Jr., was arrested on Friday on the suspicion that he mailed 13 explosives to prominent critics of President Donald Trump, the spotlight turned on a Twitter account that appears to belong to him, which he allegedly used to issue veiled threats to critics of the President. Twitter has apologized for not acting on tweets that clearly violated its terms of conduct.

After the account was surfaced on Friday, Rochelle Ritchie tweeted several screenshots of threatening tweets that @hardrock2016 sent to her. She also posted a screenshot of the Twitter’s response to her report: “we have reviewed your report carefully and found that there was no violation of the Twitter Rules against abusive behavior.”
