Senator Chuck Grassley’s office says he is in the hospital receiving treatment for an infection.

“He is in good spirits and will return to work as soon as possible following doctors’ orders,” a statement from Grassley’s office says.

Grassley is 90 years old and has been serving in the U.S. Senate representing Iowa since 1981. The Republican from New Hartford won reelection in 2022 and his term runs through 2028.
