The notes a special prosecutor called the "smoking gun" that led to the impeachment of ousted Gov. Evan Mecham were read into evidence at the former governor's fraud and perjury trial, but the man who took them said he could not remember what they meant.

Mecham and his brother and campaign treasurer, Willard Mecham, are being tried on charges they violated state law by concealing a $350,000 campaign loan from Tempe, Ariz., developer and attorney Barry Wolfson.

The "smoking gun" evidence was presented in January to the Arizona House of Representatives.
