A Twitter representative defended during a hearing Wednesday on anti-Semitism the social media site’s decision to not flag tweets from Iran Supreme Leader Ayatollah Ali Khamenei after flagging tweets from President Trump.

Khamenei has several tweets on his profile that call for the “elimination” of Israel, or “Zionist regime.” In a May 21 tweet, he wrote, “The only remedy until the removal of the Zionist regime is firm, armed resistance.”

The Twitter representative said that when political leaders’ tweets are about “comments on political issues of the day” or “foreign policy saber-rattling on military and economic issues,” they are “generally not in violation of our Twitter rules” during the hearing.
