“These documents were obtained illegally from foreign sources hostile to the United States, intended to interfere with the 2024 election and sow chaos throughout our Democratic process,” Trump campaign spokesperson Steven Cheung said in a statement.

Reuters has not independently verified the identity of the alleged hackers or their motivation.

The Trump campaign referred to a Friday report from Microsoft (MSFT.O), opens new tab researchers that said Iranian government-tied hackers tried breaking into the account of a “high-ranking official” on a U.S. presidential campaign in June. The hackers had taken over an account belonging to a former political advisor and then used it to target the official, the report said. That report did not provide further details on the targets’ identities.
