Did a JD Vance meme get tourist banned from the US?

A Norwegian tourist says he was denied entry into the US after immigration agents took issue with a meme of Vice President JD Vance on his phone.

US Homeland Security officials say he was turned away for admitting drug use.

BBC Verify's Jake Horton spoke to Mads Mikkelsen about his experience and looks at the laws which are in place for denying tourists coming into the US.
