Hillary Clinton, former Secretary of State and 2016 Democratic presidential candidate, pauses while speaking at the Service Employees International Union (SEIU) 2016 International Convention in Detroit, Michigan, U.S., on Monday, May 23, 2016. Clinton said her challenger, Senator Bernie Sanders, has "every right" to finish his campaign how he chooses, even though her extended 2008 contest for the nomination with Barack Obama was much closer than this year's battle.
