LONDON (AP) — Imagine trying to make an impression on someone who’s met, well, almost everyone.

Such is the challenge for President Joe Biden, who is set to sip tea with Queen Elizabeth II on Sunday at Windsor Castle after a Group of Seven leaders’ summit in southwestern England.

Biden, accompanied by wife, Jill, became the 13th president to meet the monarch, making her acquaintance Friday night at a reception at an indoor rainforest that she and other royals held for leaders attending a summit in Cornwall of the world’s seven largest economies.

The White House said Biden met the queen in 1982, but that was when he was a U.S. senator.

The now-95-year-old monarch has met every American president since Dwight Eisenhower during her nearly 70-year reign, except for Lyndon Johnson, who didn’t visit Britain while he was in office.
