On the other side was a man named Nils Bildt, who was identified onscreen and verbally as a "Swedish defense and national security advisor".
"We don't know this guy", Mikael Abramsson, a spokesman for the Swedish military, told the paper.
"The narrative in Sweden, the political debate is completely false", Bildt told O'Reilly. Swedish officials in the Swedish Defense Ministry and Foreign Office said that they had never heard of Bildt, and that he was not associated with any part of Sweden's government. As it turns out, Nils Bildt isn't even the man's real name and he has no affiliation with any Swedish defense or security organs.
Nils Bildt said it was his professional opinion that crime was running rampant in Sweden because of an influx in migration.
Rasmus Eljanskog, a spokesman for the Ministry of Foreign Affairs, said nobody by this name worked at the ministry. "If you don't agree with the liberal, common agenda you are viewed as an outsider and not taken seriously", he added. Bildt was born in Sweden, the son of Sven Tolling, who is apparently well-known in equestrian circles.
According to Dagens Nyheter, Nils Bildt was born Nils Tolling, who emigrated to the USA in 1994 and changed his name in the early 2000s.
Fit again, Sexton returns to Ireland team to face France
Sexton's return to the starting XV is one of three changes to the side that thrashed Italy 63-10 a fortnight ago. Yoann Huget, Rabah Slimani and Bernard Le Roux all return.
On Sunday, the newspaper Aftonbladet reported that Bildt had expressed interest in 2013 in running for office in Sweden with the nationalist right-wing party Sweden Democrats. He also has a criminal record. 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.
Bildt also denied that he falsely represented himself and claimed Fox News gave him the title of Swedish defense and national security advisor. Later, he followed up to dispute the claim he had served time in prison. "The title was chosen by Fox News's editor - I had no personal control over what title they chose".
Fox News's "The O'Reilly Factor" this week featured a guest with inaccurate credentials, The Washington Post reported Saturday.
So until O'Reilly addresses the situation tomorrow, Twitter has its own best guesses, theories and snipes about Bildt.
When asked by the Intercept how this mistake happened, Fox said that "our booker made numerous inquiries and spoke to people who recommended Nils Bildt and after pre-interviewing him and reviewing his bio, we agreed that he would make a good guest for the topic that evening".
