The opening ceremony of the Milano Cortina 2026 Winter Olympics on Friday was marked by audible boos from the crowd as delegations from the US and Israel entered the San Siro stadium, Anadolu reports.

US Vice President JD Vance and Secretary of State Marco Rubio led the American delegation.

As Vance appeared on the stadium’s big screen, waving the US flag, the crowd responded with jeers, according to live coverage of the event.

“There is the Vice President JD Vance and his wife Usha. Oops — those are a lot of boos for him,” an announcer was heard saying during the broadcast.

The reaction followed days of tension surrounding the participation of US Immigration and Customs Enforcement (ICE) agents in Olympic security.
