WASHINGTON, June 30 (Reuters) - Iran-linked hackers have threatened to disclose more emails stolen from U.S. President Donald Trump's circle, after distributing a prior batch to the media ahead of the 2024 U.S. election.
In online chats with Reuters on Sunday and Monday, the hackers, who go by the pseudonym Robert, said they had roughly 100 gigabytes of emails from the accounts of White House Chief of Staff Susie Wiles, Trump lawyer Lindsey Halligan, Trump adviser Roger Stone and porn star-turned-Trump antagonist Stormy Daniels.
