Bill O’Reilly and Fox News have been lambasted for providing fake news after interviewing a “Swedish Defense and National Security advisor,” in relation to Trump’s #LastNightInSweden gaffe, who no one had ever heard of.

Fox News host and controversial peddler of alternative facts Bill O’Reilly interviewed “Swedish Defense and National Security Adviser” Nils Bildt on Thursday, in an effort to back up the claims made about Sweden’s immigration in a Fox segment that is thought to have inspired Trump’s #lastnightinSweden comments.

Bildt dutifully echoed the claims made by Trump, claiming Swedish authorities were failing to socially integrate refugees, leading to a problem with “socially deviant activity” and “hotspots of crime.”

In an awkward turn of events, both the Swedish defense and foreign ministry have denied having any knowledge of who Bildt is.

O'Reilly had a guest PRETENDING to be a Swedish national security advisor who hasn't lived in Sweden since 1994. A total con artist. Ask why — Greg Poehler (@GregPoehler) February 24, 2017

"We have no spokesman by that name," Marie Pisäter, of the Defense Ministry, told Dagens Nyheter.

"We do not know who he is," the Foreign Office said. The Swedish Armed Forces have also stated he is “definitely not a spokesman for the Armed Forces.”

In fact, Bildt left Sweden in 1994, and changed his name from Tolling in 2003. In 2014, Bildt was convicted for assaulting a law enforcement officer and threatening an official by the Arlington General District Court in Virginia, and given a one-year prison sentence.

So @FoxNews This is Nils G Tolling and he's not known in our circles as an expert. Not on National Security anyway. pic.twitter.com/2MVu85mhWr — Johan Wiktorin (@forsvarsakerhet) February 24, 2017

He runs security companies in the US, although Dangens Nyheter said it is unclear if those companies are in operation.

Bildt later denied claiming he was a Swedish security expert, taking a leaf out of Trump’s book in blaming Fox.

"I had no control over the choice of title, which was made by Fox News' editor,” he told Dagens Nyheter. “I am an independent analyst based in the USA."
