Fox News commentator Bill O’Reilly says he could have been clearer about a man who appeared on his show last week billed as a Swedish national security adviser. Responding to criticism from officials in Sweden and liberal observers, O’Reilly said on Monday night’s episode of “The O’Reilly Factor” that he should have explained that Nils Bildt had no role in the Swedish government.

A trans-Atlantic wave of puzzlement is rippling across Sweden for the second time in a week, after a prominent Fox News program featured a “Swedish defense and national security advisor” who’s unknown to the country’s military and foreign-affairs officials. Swedes, and some Americans, have been wondering about representations of the Nordic nation in the U.S. since President Donald Trump invoked “what’s happening last night in Sweden” while alluding to past terror attacks in Europe during a rally Feb. 18. There hadn’t been any major incident in Sweden the previous night.

Fox News’s Bill O’Reilly says President Trump must exercise caution on his temporary ban on visitors from seven Muslim-majority nations. “President Trump is being responsible setting up new refugee standards as long as they are fully explained and expedited in a timely manner,” he said during Monday’s broadcast of “The O’Reilly Factor.”
