German officials, aware of Biden’s fatigue at night, sought to accommodate the president by planning a June 2022 event with German Chancellor Olaf Scholz in the early evening.

The informal event, a soiree at the Alpine resort Schloss Elmau during the Group of Seven summit, was arranged as a confidential meeting on Ukraine in a relaxed setting. Biden didn’t show, surprising the chancellor and his aides, officials said. Instead, Secretary of State Antony Blinken arrived and announced that Biden had to go to bed, according to two people who were there.
