(CNN) A self-described "email prankster" in the UK fooled a number of White House officials into thinking he was other officials, including an episode where he convinced the White House official tasked with cyber security that he was Jared Kushner and received that official's private email address unsolicited. "Tom, we are arranging a bit of a soirée towards the end of August," the fake Jared Kushner on an Outlook account wrote to the official White House email account of Homeland Security Adviser Tom Bossert. Also, if you ever need it, my personal email is" (redacted). EMAIL PRANKSTER (@SINON_REBORN) Reince (me) giving @Scaramucci something to think about. "We take all cyber related issues very seriously and are looking into these incidents further," White House press secretary Sarah Huckabee Sanders told CNN. One such exchange appears to have possibly played a role in the tensions between then- White House Communications Director Anthony Scaramucci, who resigned from his job earlier today, and since-fired White House Chief of Staff Reince Priebus. In a series of emails, the man posing as Priebus baited Scaramucci, accusing him of being “breathtakingly hypocritical” and saying “at no stage have you acted in a way that is remotely classy”. The very real Scaramucci responded: "You know what you did. Even today. But rest assured we were prepared. A Man would apologize.” 
 
 The heated exchange continued, with the prankster writing: “I can’t believe you are questioning my ethics! The so called 'Mooch', who can't even manage his first week in the White House without leaving upset in his wake. I have nothing to apologize for.” 
 
 Scaramucci replied: “Read Shakespeare. Particularly Othello. You are right there. My family is fine by the way and will thrive. I know what you did. No more replies from me.” 
 
 The White House has confirmed it is looking into the matter. In another exchange, Scaramucci was hoodwinked by the same prankster pretending to be Ambassador to Russia-designate Jon Huntsman Jr. 
 
 "Who's (sic) head should roll first?" “I’m not trying to get the keys to the vault or anything like that.” 
 
 
 
 He has previously convinced Scaramucci that he was the ambassador to Russia-designate Jon Hunstman and tricked Hunstman himself into believing he was the president’s son Eric Trump. Eric Trump, too, was similarly hoodwinked by the prankster emailing as his older brother, Donald Trump Jr., but he soon caught on and responded, "I have sent this to law enforcement who will handle from here."
– Former White House communications director Anthony Scaramucci wasn't on the job for long—but it was long enough to be taken in by an email prankster who impersonated other officials. In emails to Scaramucci, the prankster pretended to be Reince Priebus and may have escalated tensions between the two men, the Guardian reports. After Priebus was fired as White House chief of staff, his impersonator told Scaramucci: "General Kelly will do a fine job. I'll even admit he will do a better job than me. But the way in which that transition has come about has been diabolical. And hurtful." Scaramucci replied: "You know what you did. We all do. Even today. But rest assured we were prepared. A Man would apologize." "I can't believe you are questioning my ethics! The so called 'Mooch,' who can’t even manage his first week in the White House without leaving upset in his wake," the fake Priebus wrote. The real Scaramucci replied: "Read Shakespeare. Particularly Othello ... I know what you did. No more replies from me." In other emails, the prankster—who describes himself as a "lazy anarchist" and uses the Twitter handle @SINON_REBORN—convinces Homeland Security Adviser Tom Bossert he is Jared Kushner, convinces Scaramucci that he is Ambassador to Russia-designate Jon Huntsman Jr., and convinces Huntsman that he is Eric Trump, CNN reports. The White House says it is investigating.
