U.S. authorities are preparing to file criminal charges related to a hack of Donald Trump's presidential campaign, with the Iranian government being blamed for the intrusion. The hack, disclosed by the Trump campaign on August 10, involved the theft and distribution of sensitive internal documents. The FBI is investigating a persona named 'Robert,' who allegedly shared documents falsely claiming to be sourced from the campaign. While the Iranian government has denied involvement, Assistant Attorney General Matthew Olsen indicated Iran's efforts to influence U.S. elections are increasing. This situation highlights ongoing cybersecurity threats to political entities in the U.S. as the election approaches.
