Defense Secretary Lloyd Austin approved a request from the Department of Homeland Security on Thursday for the Pentagon to provide the Secret Service with additional resources for the presidential and vice presidential candidates.

The Secret Service and the safety of the candidates have become a significant concern following last month’s assassination attempt against former President Donald Trump, as well as a plot by the Iranians to kill him and anyone else from his first administration who was involved in the January 2020 assassination of Iranian military Gen. Qassem Soleimani.
