Right-wingers are salivating, in their dreams. They think that Nancy Pelosi has violated the Logan Act.
My first thought is whether the Logan Act been tested in front of the Supreme Court?
Short of a person (who is not part of the Executive) explicitly engaging in negotiating a treaty, it seems to me that the Logan Act is totally un-enforceable. For example, when Bill Gates meets with the Premier of China, is that a violation of the Logan Act? If so, then modern capitalist enterprise is impossible as so much of it requires detailed interaction with foreign officials.
Consider the enforceability of Sec 953. Private correspondence with foreign governments, which reads:
Any citizen of the United States, wherever he may be, who, without authority of the United States, directly or indirectly commences or carries on any correspondence or intercourse with any foreign government or any officer or agent thereof, with intent to influence the measures or conduct of any foreign government or of any officer or agent thereof, in relation to any disputes or controversies with the United States...
Based on the language of the Act, it would seem likely, as it's hard to imagine that Bill Gates (in both his role as head of Microsoft and of the Gates Foundation) and the Premier of China discuss only golf and bridge.
So what the Supremes have said on the matter? Not much, I gather, as there have been very few if any prosecutions under it. (See Logan Act at Wikipedia, fwiw.)
My hunch is that these anti-Pelosi sentiments are an extreme example of wishful and naive thinking and an attempt to help Bush by diverting attention from his ineptness.
