BERNIE Sanders, a 2020 Democratic presidential candidate has cancelled campaigning after undergoing surgery for an arterial blockage.
The 78-year-old was treated at hospital after complaining of chest pains during an event in Nevada on Tuesday.

In a statement his senior adviser Jeff Weaver said, “Following medical evaluation and testing he was found to have a blockage in one artery and two stents were successfully inserted.”

It was still unclear when Sanders will resume campaigning.
