The Logan Act clearly states in § 953 Private correspondence with foreign governments
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, or to defeat the measures of the United States, shall be fined under this title or imprisoned not more than three years, or both.
This section shall not abridge the right of a citizen to apply himself, or his agent, to any foreign government, or the agents thereof, for redress of any injury which he may have sustained from such government or any of its agents or subjects."

The broke this law by pushing for a UN intervention (Foreign Agents) with the intent to limit internet free speech which violates the 1st amendment of the US. As such they violated this law.

How can we let this slide? Even though the punishment would not be great, how could we let someone with the intent to limit our free speech by influencing countries around us to convince them to go on board with this! They clearly violated the Logan Act and as such they should be put in jail or fined.
