A catfish posing as Susie Wiles, Donald Trump’s chief of staff, texted and called her contacts asking for cash and presidential pardons, it has been reported.

Ms Wiles, who is considered the most powerful woman in the White House, has privately told colleagues her personal cell phone was hacked and mined for executive contacts.

The FBI has launched an investigation following the breach.

The impostor is said to have sent a series of text messages and phone calls to Republican lawmakers using Artificial Intelligence to mimic her voice, according to the Wall Street Journal.

In one case, the impersonator is said to have asked for a cash transfer and in another, asked a lawmaker to put together a list of people who could be pardoned by Donald Trump.
