Mayor Eugene Sawyer says he filed some federal income tax returns late but says he violated no laws and owed the government no money.

Sawyer blamed the late filings in part on his accountant's frequent hospitalization, but his political rivals were quick to criticize the delays.Television station WBBM reported that Sawyer's return for 1986 was filed more than a year late and said he also missed the deadline for filing his 1987 return. Both were filed last summer, the report said.
