The footage shows Joe Biden walking into the veranda of the restaurant where the journalists are sitting, stopping and looking around.
“How is the Cornwall summit going?” the audience asked him.
The head of the White House assessed the events as “very good” and continued, apparently, to look for his wife Jill, who later appeared from the other side of the veranda and called the American leader.
Joe Biden is currently in the UK. On Wednesday, the US president began his first foreign tour since taking office, in which he will attend a meeting of the leaders of the “Big Seven” in Cornwall, meet with NATO heads of state and representatives of the European Union in Brussels and hold bilateral talks in Geneva with Vladimir Putin.
