U.S. President Joe Biden was caught by the cameras dozing off briefly during the 26th Conference of Parties (COP26) climate conference in Glasgow on Monday, just before his own speech.
According to a report by metro.co.uk, Biden was captured on video sitting at the United Nations conference, with his arms crossed.
He closed his eyes for several seconds at a time during the opening speeches.
At one point, he appeared to doze off for at least 15 seconds until a man approached him and whispered something into his ear.
The US president later addressed world leaders.
