VIDEO: Mathematical Puzzle. Biden Surprises Everyone Again

American leader Joe Biden has surprised everyone again during one of his speeches, this time showcasing his mathematical knowledge.

The matter is that Biden stated that his younger sister was 3 years younger than him; now she is 23 years younger.

Not long ago, during an event, U.S. President Joe Biden started searching for member of Congress Jackie Walorski among the attendees, who had died in a car accident in August.

Later, White House Press Secretary Karine Jean-Pierre tried to explain the incident during a briefing. She assured those present that Biden had not mixed anything up, but was simply remembering the late Congresswoman by “recognizing her significant work.”
