(WASHINGTON) — Rep. Steve Scalise, the No. 2-ranking House Republican, said Tuesday he has been diagnosed with a form of blood cancer known as multiple myeloma and is undergoing treatment. Scalise, 57, said he will continue to serve in the House. He described the cancer as “very treatable” and said it was detected early.
