US President Joe Biden confuses Angela Merkel with Helmut Kohl. It is Biden's second blunder of this kind in a short period of time.

The mistake comes just a few days after Biden confused the current French President Emmanuel Macron with his predecessor François Mitterrand, who died almost 30 years ago. Biden, the oldest sitting president of the United States, has had similar public outbursts on several occasions. But his competitor Donald Trump, 77, has also misidentified people.
