UPDATE 1:30 P.M.
An update from the Lewis campaign states that the former congressman has undergone a successful surgery and is recovering.
"I am very pleased to report that according to Congressman Lewis’ doctor, his emergency surgery this morning to treat an internal hernia was successful and minimally invasive," it said.
"Provided that his recovery continues on a positive trajectory, doctors anticipate that he is likely to be released from the hospital in the next couple of days."
Senate candidate Jason Lewis was rushed into emergency surgery Monday for a "life-threatening" hernia.
Lewis' campaign manager Tom Szymanski said in a statement that Lewis was rushed to the emergency room with "severe abdominal pain."
Doctors determined he was suffering a "severe internal hernia," which can be life-threatening if not treated quickly. He was then rushed into emergency surgery.
Prior to be taken into surgery, Lewis was in "good spirits, optimistic, and true to form, he was speculating about when he could resume campaigning, eager to continue fighting for his fellow Minnesotans," Szymanski said.
Lewis' campaigning has already been stymied by the fact he has had to quarantine twice following exposures to people who later tested positive for COVID-19, though his campaign says he has not tested positive himself.
The Republican is running against Sen. Tina Smith for her U.S. Senate seat.
