The Arizona Senate on a voice vote granted Gov. Evan Mecham a one-week delay of his impeachment trial set to begin Monday. Earlier in the day, the Senate defeated two motions for delay offered by the embattled governor's attorney, Murray Miller. Miller had asked that the trial be put off until criminal charges of concealing a $350,000 campaign loan are adjudicated. The House impeached Mecham Feb. 5 and accused him of concealing the loan, misusing $80,000 from the governor's protocol fund by loaning it to his auto dealership, and trying to thwart a probe of an alleged death threat by a state official.
