Initial reports about the discovery of suspicious mail by the Lake campaign last weekend mentioned only the first envelope, and nothing was said at the time about it being tossed into the trash and carted away before it could be studied.
Phoenix police and fire officials said they were called to the building last weekend on a report of an envelope containing suspicious white powder.
Police said at the time that there were no reports of injuries or illness, though Lake’s campaign had said the staff member who opened the envelope was under medical supervision.
The gubernatorial race between Lake and Democrat Katie Hobbs in the crucial battleground state remained too early to call as of Saturday morning. It often takes days to know the results of key races in Arizona.
