US Vice President Kamala Harris addresses pro-Palestinian protesters at her Arizona rally on Aug. 9, telling them she respects their voices and also calling for a ceasefire in Gaza. The Uncommitted political group was organized to oppose President Joe Biden's staunch support for Israel's war, which has killed tens of thousands, displaced nearly 80 percent of Gaza's 2.3 million people and caused severe food shortages. The humanitarian catastrophe in Gaza has prompted calls for Washington to put conditions on the billions of dollars in military funding and other assistance it provides to Israel, which has received more US foreign aid since World War II than any other country.REUTERS VIDEO
