US Treasury Secretary Scott Bessent recently moved out of his home and onto a military base after Iranian threats against his life, according to three people with knowledge of the matter, The New York Times reports.

US officials concluded in recent weeks that Iranian plotting against current and former American officials had reached a more advanced stage, based in part on intelligence about threats to Bessent, according to the people.

Since August, Bessent has led an economic pressure campaign meant to isolate Iran financially through tougher sanctions and restrictions on trade routes. That role has made him one of the administration officials that Iran most wants to harm, the people said.

But the severity of the threats to him is unclear.

In a statement, a Treasury Department spokesperson said Bessent “will not be deterred by the Iranian regime’s threats,” adding that he remains committed to executing the campaign to squeeze Iran’s economy.
