The main targets are the Judiciary Committee Democrats pictured below. The ones whose names are in bold face already support holding impeachment hearings:
Chairman Conyers Rep. Berman Rep. Nadler Rep. Rick Boucher
Rep Scott Rep. Baldwin Rep. Watt Rep. Waters
Rep. Jackson Lee Rep. Wexler Rep. Lofgren Rep. Schiff
Rep. Ellison Rep. Sánchez Rep. Weiner Rep. Gutierrez
Rep. Johnson Rep. Sherman Rep. Davis Rep. Delahunt
Rep. Cohen Rep. Sutton Rep. Wasserman Schultz
Here are the names, contact information and links to the above Democrats' Web sites. They are most likely to listen to constituents from their own districts, naturally. But that shouldn’t stop you from phoning, writing or e-mailing one or more of them, urging them to do what you believe needs to be done. DocGonzo has provided some direct e-mail links (plus district ZIP Codes in case you're asked for that when you send an e-mail here).
