Turns out Russia's email hacking scandal isn't the only issue harassing the Trump administration.
Several senior White House officials were tricked by a UK-based email prankster after he sent them a series of messages impersonating other top Trump administration aides.
Email prankster tricks senior White House officials
Prankster may have stirred Priebus-Scaramucci row
The prankster used a mail.com account to message Scaramucci by impersonating former chief of staff Reince Priebus, a day after the latter resigned.
The fake Priebus called one of Scaramucci's tweets "breathtakingly hypocritical." Scaramucci replied calling on Priebus to "apologize."
Scaramucci had called Priebus a "f**king paranoid schizophrenic" in a profanity-laden interview that led to his quick dismissal, 10 days after his appointment.
Top cyber security official fooled by Kushner impersonation
The prankster also duped Homeland Security Adviser Tom Bossert, who handles cyber security, into believing that he was President Donald Trump's son-in-law Jared Kushner.
The fake Kushner invited Bossert for "a bit of a soirée."
Bossert wrote back: "Thanks, Jared. With a promise like that, I can't refuse."
Bossert also divulged his personal email ID.

The prankster said he hadn't heard from law enforcement despite Donald Trump Jr.'s threat.
