Kash Patel, chosen by US President-elect Donald Trump to lead the FBI, was recently notified by the bureau that he was a target of an Iranian hack, two sources familiar with the situation told CNN.

Hackers accessed at least some of Patel’s communications, according to one source.

“Kash Patel was a key part of the first Trump administration’s efforts against the terrorist Iranian regime and will implement President Trump’s policies to protect America from adversaries as the FBI Director,” Trump transition spokesman Alex Pfeiffer said in an statement.
