A video of Italian Prime Minister Giorgia Meloni rolling her eyes while waiting for US President Joe Biden at the NATO summit has gone viral online.

The video, shot Thursday morning, shows Meloni rolling her eyes and checking a nonexistent watch while waiting with other leaders for Biden and NATO Secretary General Jens Stoltenberg.

The summit was scheduled to start at 10 am but began at 10:40 am due to Biden's delay.

Another person with Meloni checked the time on his phone, prompting her to roll her eyes again before noticing the cameras.

Biden's delay also caused his solo press conference to be pushed back by the White House.
