(RNN/CNN) - Homeland security adviser Tom Bossert became one of many White House staffers to fall victim to an email prank Monday.
The self-described “email prankster” in the U.K. sent a letter to Bossert, pretending to be President Trump's son-in-law Jared Kushner.
The emails were shared with CNN by the email prankster.
"Tom, we are arranging a bit of a soirée towards the end of August,” the fake Kushner sent. "It would be great if you could make it, I promise food of at least comparable quality to that which we ate in Iraq. Should be a great evening."
"Thanks, Jared. With a promise like that, I can't refuse,” Bossert responded.
Bossert gave the man his personal email unsolicited, in a gesture that surprised even the prankster himself.

The prankster fooled a number of White House officials the same way by pretending to be other officials, including former White House Communications Director Anthony Scaramucci.
The man emailed Scaramucci, pretending to be former White House Chief of Staff Reince Priebus responding to one of Scaramucci's tweets in a previous prank.
"At no stage have you acted in a way that's even remotely classy, yet you believe that's the standard by which everyone should behave towards you," the fake Priebus said.
"You know what you did. We all do. Even today. But rest assured we were prepared. A Man would apologize," the real Scaramucci responded.
The prankster also tricked Eric Trump, posing as his brother Donald Jr. Eric soon caught on to the fake and responded, “I have sent this to law enforcement who will handle from here.”
The prankster told CNN that he never heard from law enforcement.
White House officials acknowledged the incidents, and said they were taking the matter seriously.
