House Speaker Nancy Pelosi is being honoured with the 2019 John F Kennedy Profile in Courage Award.
Pelosi is being recognised for her efforts to pass former President Barack Obama's 2010 health care law and for helping Democrats reclaim control of the US House during last year's elections.
Caroline Kennedy, the daughter of the late president, calls the California Democrat "the most important woman in American political history."
Kennedy said Pelosi, who has served in the House since 1987, "leads with strength, integrity and grace under pressure."
