Former New York City Mayor Ed Koch will remain in the hospital until Friday, spokesman George Arzt said in a statement this evening.

His statement:

“Former Mayor Ed Koch will remain in New York/Presbyterian Weill-Cornell Medical Center for a couple of more days. He expects to go home on Friday.”

Koch was sent to the hospital yesterday for anemia and received a blood transfusion.

The former mayor, naturally, is still opinionated self, complaining about the ill-fated plank on Jerusalem that was later amended.
