Former U.S. House Speaker Nancy Pelosi, 84, has been hospitalized in Luxembourg after sustaining an injury while attending an official diplomatic event, as confirmed by her office. Pelosi, a prominent Democratic leader, was in Europe as part of a bipartisan congressional delegation marking the 80th anniversary of the Battle of the Bulge — a pivotal World War II battle that symbolizes the enduring bond and sacrifices between the U.S. and its European allies.
