WASHINGTON (Reuters) - U.S. Representative Steny Hoyer, the No. 2 Democrat in the House of Representatives, has been hospitalized with pneumonia and is expected to make a quick recovery, his office said on Wednesday.

Hoyer, 79, of Maryland, was admitted to the George Washington University Hospital on Tuesday and diagnosed with pneumonia, spokeswoman Katie Grant said.

“He is being treated with antibiotics and resting, and is expected to make a full recovery quickly,” Grant said in a statement.

Politico, which first reported the hospitalization, said Hoyer had campaigned over the weekend with Democratic incumbents and swing district candidates in Wisconsin and Illinois.
