WASHINGTON (AA) - Leading Democratic presidential candidate, Senator Bernie Sanders, underwent heart surgery after he experienced chest pains during a campaign event in Las Vegas, Nevada, his campaign adviser said Wednesday.
"Sanders is conversing and in good spirits. He will be resting up over the next few days," said Jeff Weaver.
Weaver said a medical evaluation of the 78-year-old senator discovered blockage in one of his arteries, and two stents were successfully inserted Tuesday.
"We are canceling his events and appearances until further notice, and we will continue to provide appropriate updates," Weaver added.
In a tweet, Sen. Kamala Harris wished Sanders a "speedy recovery."
"Thinking of @BernieSanders today and wishing him a speedy recovery. If there's one thing I know about him, he's a fighter and I look forward to seeing him on the campaign trail soon," she tweeted.
Sanders raised $25.3 million during the past three months for his White House race.
The senator had committed to releasing his medical records before primary voting begins, according to a CNBC report.
Sanders released a doctor report, confirming his well being during his 2016 presidential campaign.
If elected, the Vermont senator would be the oldest president to serve.
