Coming out of today's meeting with John Conyers, these seem to be the significant developments:
He is circulating a letter among his colleageus for signatures, a letter addressed to Bush letting him know that an attack on Iran will result in impeachment hearings. LET'S ASK EVERY MEMBER OF CONGRESS TO SIGN ON! I know it seems bassackwards and we want impeachment before a new war, not after, but this is a way for us to show Conyers the support that will be there any time he moves forward.
He is open to the new argument that we have been making to him, namely that impeachment hearings for Cheney or Bush (on torture, signing statements, spying, war crimes, etc, etc) would hurt John McCain's candidacy by forcing him to defend the crimes.
He is open to meeting with experts allied with us to hear their arguments for impeachment.
All of that is positive. Still, Conyers continues to believe that elections are more important than justice, that impeachment would be bad for the elections, and that impeachment hearings would be stonewalled by the White House. There are a couple of possible responses to the last point. One is that impeachment hearings, including taking up H Res 799 as instructed by the full House last November, and even marking it up to add new charges, overrule claims of "executive privilege." Of course Bush and Cheney could claim otherwise, but there is an answer to that. When Nixon refused a subpoena, the House Judiciary Committee passed an article of impeachment against him for that refusal. Cheney and Bush have already refused subpoenas. There's no need to wait.
