From the so-called “president’s” ghost-written effusion, The Art of the Deal:
Mayor Koch has achieved something quite miraculous. He’s presided over an administration that is both pervasively corrupt and totally incompetent . . . . No fewer than a dozen Koch appointees and cohorts have been indicted on charges of bribery, perjury, and accepting kickbacks, or have been forced to resign in disgrace after admitting ethical transgressions . . . . The irony is that Koch made his reputation by boasting about his integrity and incorruptibility. It doesn’t seem to occur to him that if the people he appoints prove to be corrupt, then in the end he must take the responsibility. To the contrary, at the first hint that any of his friends might be in trouble, Koch can’t run fast enough the other way.
