The U.S. government is investigating after elected officials, business executives and other prominent figures received messages in recent weeks from someone impersonating Susie Wiles, President Donald Trump’s chief of staff.

President Donald Trump said someone hacked his chief of staff’s phone, just weeks after the FBI warned of “malicious actors” impersonating senior officials.

A federal investigation is underway after elected officials and other prominent figures were contacted by an imposter pretending to be Chief of Staff Susie Wiles.
