Former New York City Mayor Ed Koch is in the hospital today after being admitted with a respiratory infection, his spokesman George Arzt said this afternoon.

Koch, who turns 88 next week, is being treated with antibiotics at the New York-Presbyterian Hospital, Arzt said.

The former mayor was admitted to the hospital back in September, the same week as the Democratic National Convention in Charlotte and was treated for anemia.

Koch in recent years became a force for good-government in New York, pushing lawmakers and legislative candidates to run on his platform of independent redistricting and ethics reform in Albany.
