Mr. Reid had been quietly letting people know over the past few days that he would be undergoing surgery, including former President Barack Obama. He was succeeded by Minority Leader Chuck Schumer (D-N.Y.), who said that he spoke to Reid's family on Monday and that "it seems [Reid's] operation went well".
Former Democratic U.S. Senate Majority Leader Harry Reid had surgery on Monday to remove a tumor from his pancreas, according to a family statement posted on his Facebook page. "He is now out of surgery, in good spirits and resting with his family".
The former senator's family said they were confident the surgery was successful.
Mr. Reid was first elected to the Senate in 1986 and became the Democratic leader in 2005. The Senator opted against running for re-election in 2015; that same year he suffered from a brutal accident that left him blind in one eye.
Reid, 78, has spent most of his time in retirement in Las Vegas and has traveled to Washington just a handful of times, according to a person familiar with his travels. He now co-chairs the MGM Resorts International Public Policy Institute with former House Speaker John Boehner. Senator Catherine Cortez Masto says "Senator Reid is no stranger to a fight". "Harry is a fighter - literally and figuratively - I know he is going to approach his recovery with the same energy and tenacity and resolve that defined his public life".
