PresidentJoe Bidenmet withKing Charlesat Windsor Castle, but the trip will be without the full glamour that sometimes comes with foreign visits to the United Kingdom.
Earlier in the day, Biden met British Prime Minister Rishi Sunak. From the U.K., the president will travel to Lithuania for the NATO Summit and Finland for a U.S.-Nordic Leaders Summit, the White House said.
A U.S. state visit may occur at a later date — in April, the White House said that Biden accepted King Charles' invitation for a state visit during a phone call ahead of the monarch’s coronation.
