A Norwegian tourist says he was denied entry after U.S. border authorities found a meme of JD Vance on his phone, but DHS says otherwise.

US officials have denied claims that a Norwegian man was sent home because of a meme - but the case has raised international questions.

Mikkelsen said that the entire episode had been traumatic because of strip-searches, luggage ransacking, fingerprinting, blood sampling and falsified travel records. His Norwegian passport had also been mistakenly labelled as "Spanish".
