An Iran-linked hacker group calling itself “Robert” claims to have stolen over 100 gigabytes of emails from Donald Trump’s inner circle and is threatening to release them in what U.S. officials call a politically motivated smear campaign.

Targets reportedly include Trump allies like Susie Wiles, Roger Stone, and attorney Lindsey Halligan.

U.S. authorities have tied the group to Iran’s Islamic Revolutionary Guard Corps.

The hackers say the breach was retaliation for recent U.S. involvement in an Israel-Iran conflict, Mediaite has reported.

Officials dismiss the threat as propaganda aimed at discrediting Trump and his associates.
