Time to Logan Act that uppity wench. Editing to add: She's walking a very fine line. Here's a quote from the article:  During her speech at the 2019 United Nations Climate Conference, Pelosi said, "this is a mission, this is a passion, this is a scientifically-based approach, to all that ... We are here to say to all of you, on behalf of the House of Representatives and the Congress of the United States, 'we're still in it.'"  Logan Act the lot of them. Start with her and John Kerry.
