Bernie Sanders had artery blockage, stents inserted, off the campaign trail for now

Senator Bernie Sanders is off the campaign trail "until further notice" after physicians discovered a blockage in one of his arteries and inserted two stents. He had experienced "chest discomfort" last night. From CNN:

"Sen. Sanders is conversing and in good spirits," (said senior adviser Jeff Weaver.) "He will be resting up over the next few days. We are canceling his events and appearances until further notice, and we will continue to provide appropriate updates..."

Sanders, who is 78 years old, felt the "discomfort" during a campaign event. Despite his age, he has been one of the most active campaigners in the 2020 Democratic primary field.
