Iran provided a written assurance to the Biden administration last month that it would not seek to assassinate then-GOP nominee Donald Trump. The October 14 message was aimed at easing tensions between Tehran and Washington ahead of Trump’s potential return, as per the WSJ. The US sent Iran a “private written warning” in September that Washington would consider an attempt on Trump’s life as an act of war. The US Justice Department last week outlined allegations that Iranian agents plotted to assassinate Trump before he was re-elected as president. US federal prosecutors in August charged a Pakistani man with alleged ties to Iran with plotting to kill Trump.
