Sanders arrives back in Vermont after heart attack

US Democratic presidential candidate Bernie Sanders said he's "feeling great" after flying home to Vermont, following treatment for a heart attack. The 78-year-old was questioned by reporters about his health as he arrived at Burlington Airport on Saturday. He was taken to hospital in Las Vegas after experiencing chest discomfort at a campaign event on Tuesday. Sanders' campaign released a statement from his doctors that said two stents were inserted to open up a blocked artery in his heart. They say the rest of his arteries were normal.
