  On August 10, 2022, an Iranian national and member of Iran's Islamic Revolutionary Guard Corps, Shahram Poursafi, was charged by the United States Department of Justice in an October 2021 plot to murder Bolton, likely in retaliation for the January 2020 death of Qasem Soleimani. In response to the plot, Bolton was granted a protective detail from the United States Secret Service on the orders of President Joe Biden.
