Iowa Republican Sen. Chuck Grassley will undergo open heart surgery, his office has announced.
Grassley, 89, previously injured his hip in an as-yet-unspecified incident, but is expected to make a full recovery, according to The Hill.
The senior lawmaker won an eighth term as Senator in the November 2022 midterms, easily triumphing over his Democratic opponent.
Iowa GOP Sen. Joni Ernst expressed her well-wishes on Twitter, saying “Join me in praying for a speedy recovery for [Grassley]. I know he’ll be back on his 4am running routine in no time!”
