WASHINGTON (AP) — A top official in Bernie Sanders’ presidential campaign says the Democratic candidate is in Las Vegas where he’s resting after having a heart procedure for a blocked artery. Campaign adviser Jeff Weaver says that Sanders’ wife, Jane O’Meara Sanders, is on her way to Las Vegas. The campaign says the 78-year-old Sanders experienced chest discomfort during an event Tuesday and sought medical evaluation. Sanders has canceled events and appearances “until further notice.”
