WASHINGTON (AP) — Myanmar democracy leader Aung San Suu Kyi, renowned for her peaceful struggle against military rule, began a marathon tour of the U.S. Monday, the latest milestone in her remarkable journey from political prisoner to globe-trotting stateswoman.

The Nobel Peace laureate will be presented with Congress’ highest award during a 17-day visit that comes as the Obama administration considers easing remaining sanctions on the country, also known as Burma. In the latest step toward political opening, Myanmar announced a new round of prisoner releases, hours before Suu Kyi touched down in Washington.
