Trump Receives Warning of Alleged Iranian Assassination Threats

US presidential candidate Donald Trump has been briefed by US intelligence officials on alleged threats from Iran to assassinate him. Iran has previously denied US claims of interfering in American affairs. A Pakistani man with alleged ties to Iran pleaded not guilty to charges stemming from an alleged plot earlier this month. The Iranian government has not commented on the matter. Trump has responded by stating that the US will take strong action against Iran if necessary, and that American leaders will be considered "gutless cowards" if they do not take action.
