Weaver delivered the news about the senator’s health during a conference call around 10:30 a.m. ET, an aide told CNN. He read the statement that was later released and did not elaborate.
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.
A campaign aide told CNN that Sanders arrived in Las Vegas on Tuesday at around 5:30 p.m. local time. He then visited the Las Vegas Community Healing Garden to pay tribute on the second anniversary of the October 1, 2017, mass shooting there.
Minutes after the news of Sanders’ procedure became public, his campaign rivals responded with an outpouring of support.
“Bruce, Team Warren, and I are sending all our best wishes for a speedy recovery to @BernieSanders,” Sen. Elizabeth Warren, one of Sanders’ closest allies in Washington, tweeted. “I hope to see my friend back on the campaign trail very soon.”
South Bend, Indiana, Mayor Pete Buttigieg also wished Sanders well.
“All of us here at @PeteForAmerica are sending our best wishes for a speedy recovery to Senator @BernieSanders,” Buttigieg tweeted. “We’re thinking of him and his family today, and I look forward to seeing him back on the campaign trail very soon.”
Sens. Kamala Harris, Amy Klobuchar and Cory Booker also tweeted out their support, along with Andrew Yang and former Housing and Urban Development secretary Julián Castro.
And former Vice President Joe Biden tweeted, “.@DrBiden and I are sending our best wishes to @BernieSanders, Jane, and the whole Sanders family. Anyone who knows Bernie understands what a force he is. We are confident that he will have a full and speedy recovery and look forward to seeing him on the trail soon.”
