WASHINGTON (AP) _ Rep. John Grotberg, R-Ill., who was comatose for five weeks, has now contracted pneumonia and is being moved to a hospital closer to his home, aides said Thursday.

Joseph Ebbesen, a special assistant to Grotberg, said the lawmaker was being moved Thursday from the Rehabilitation Institute of Chicago to Delnor Community Hospital in St. Charles, about 25 miles west of Chicago.

Grotberg, 61, had been hospitalized at the institute since April, and has been suffering from pneumonia since last week.

Terry Des Coteaux, the congressman's chief district aide, said the infection has affected Grotberg's right lung, but does not appear to be life- threatening.

Ebbesen said the family elected to bring him close to home because the pneumonia had interrupted Grotberg's physical and speech therapy at the institute.

The congressman lapsed into a coma last January after suffering complications from an experimental cancer treatment he was receiving at the National Institutes of Health in the Washington suburb of Bethesda, Md.

Grotberg emerged from the coma in early March, but has remained hospitalized since then.

Grotberg, a freshman representative, won renomination to the state's 14th congressional district seat in the March 18 primary. But he withdrew his candidacy in May after doctors said they did not believe his recovery was progressing sufficiently to permit him to campaign.
