Bernie Sanders had heart surgery

The Democratic presidential candidate Bernie Sanders is suspending his campaign appearances "until further notice" because of a heart operation. Senator Sanders is now fine, but he will rest "a few days," his campaign team said on Wednesday. After the intervention, he was in good spirits and was talking to his visitors.

The 78-year-old had a blocked artery, which is why two stents were inserted into him. He had pain in the chest area on Tuesday evening and then had a check-up, the team said. Sanders had already canceled campaign events and appearances in the US state of South Carolina in mid-September - but only to spare his voice, his campaign team announced at the time.

Sanders is the oldest candidate for the Democratic presidential nomination. He occasionally cracks jokes about his age when speaking to young people. His campaign troops are trying to present him as a candidate who has even more energy than when he ran for the 2016 election. His campaign manager Faiz Shakir emphasized that Sanders' campaign was in good shape and referred to the high level of donations in the third quarter.

The independent Senator Sanders competes against former Vice President Joe Biden (76) in the Democratic primary campaign. The old age of the two co-favorites was an issue several times. The applicant Elizabeth Warren is already 70 years old. This has sparked a debate as to whether the Democrats shouldn't give preference to a new generation of political leaders.
