Federal authorities are probing a scheme to impersonate White House chief of staff Susie Wiles, according to individuals familiar with the issue, the Wall Street Journal reported.

"The White House takes the cybersecurity of all staff very seriously, and this matter continues to be investigated," a White House official noted.

Senators, governors, American business executives and other people have gotten texts and calls from an individual claiming to be Wiles, individuals familiar with the messages noted, according to the outlet.

FBI officials informed the White House that they do not think another country is involved, some of the people noted, according to the report.
