Sen. Bernie Sanders, 78, was hospitalized in Las Vegas, Nevada.
"During a campaign event yesterday evening, Sen. Sanders experienced some chest discomfort. Following medical evaluation and testing he was found to have a blockage in one artery and two stents were successfully inserted," said Sanders’ senior adviser Jeff Weaver on Wednesday in a statement.
"Sen. Sanders is conversing and in good spirits. He will be resting up over the next few days," Weaver said. "We are canceling his events and appearances until further notice, and we will continue to provide appropriate updates."
