Impeachments are not brought about by the citizenry regardless of the number of states, or signatures received. A U.S. Congressman or Senator can raise an issue on the floor(or not) as a result of a State Legislative resolution but it carries no legal weight.
Besides, as posted previously, Members of Congress and the Senate are expelled not impeached. It will be a cold day in hell when this happens. Also, Pelosi is not covered under the Logan Act.
