For the second time in as many weeks an unmarked letter spewing a suspicious powder was sent to the office of a Georgia congressman. And for the second time the authorities determined the substance appeared to be tea.

The events this week happened in the Savannah office of freshman U.S. Rep. Buddy Carter, R-Pooler. Lithonia Democrat Hank Johnson's DeKalb County office was at the center of a virtually identical scene last week.

Here's more from our colleague Steve Burns:

"There was no threat associated with a letter nor a return address," FBI spokesman Stephen Emmett said Tuesday of the Savannah situation.

"As an added note, law enforcement officials are aware of affiliates of a political or tax protest movement mailing tea bags to congressional offices as a form of protest or other messaging. It remains to be seen if this was the case in yesterday's matter, however."
