U.S. Republican front-runner Donald Trump and Democratic favourite Hillary Clinton have both swept to victory at the primaries in Arizona. Yiming Woo reports.
Hillary Clinton extends her winning streak by taking Arizona and is on track to securing the Democratic nomination. During her victory speech in Seattle, Clinton spoke about Tuesday's attacks in Brussels that killed at least 30 people. Islamic State has claimed responsibility for the bombings. (SOUNDBITE) (English) DEMOCRATIC PRESIDENTIAL CANDIDATE, HILLARY CLINTON, SAYING: "This is a time for America to lead, not cower, and we will lead, and we will defeat terrorists who threaten us and our friends and allies." While her opponent Bernie Sanders lost out, polls show him gaining on the former secretary of state. Over in the Republican camp, Trump's victory wasn't a surprise -- his hardline immigration message is popular in Arizona, which shares a border with Mexico. He'll have a harder time in Utah, where he's lagging behind his rival, Ted Cruz.
