Hoyer, 79, of Maryland, was admitted to George Washington University Hospital on Tuesday, July 3, after being diagnosed with pneumonia.
He had campaigned the previous weekend with Democratic incumbents and swing district candidates in Wisconsin and Illinois.
"Mr. Hoyer went home from the hospital this weekend," his communications director, Katie Grant, said in a statement on Tuesday. "He thanks everyone for their well wishes and will be back on the Hill this week."
