Former FDA Commissioner Lester Crawford's sentencing on charges he lied about his stock holdings was delayed Tuesday over questions about sentencing guidelines.

Under a deal worked out between his attorney and federal prosecutors, Crawford had agreed earlier to a $50,000 fine and probation.

Magistrate Judge Deborah A. Robinson asked the attorneys to explain why they didn't use certain federal sentencing guidelines in recommending a penalty.

Sentencing was rescheduled for Feb. 27.
