Think I'd like to let this speak for itself. From the liveblogging at AfterDowningStreet.org:
...Conyers said that he has drafted and is circulating to his colleagues a letter to Bush that says that if he attacks Iran impeachment hearings will begin.
And from the update:
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.
And, of course, the action number:
You can let the House Judiciary Committee know your opinion at (202) 224-3121. Please do so right now. They're good people. I know they are. But something is blocking them. Help break the logjam!
Many thanks to David Swanson and all who attended the sit-in. While I've lost my faith in the "strongly worded letter", perhaps this move will serve to put a check on Bushco's imperial ambitions until the changing of the guard.
Minor Update:
First off, the article over at AfterDowningStreet.org has been updated with a picture of the meeting. Some additional ones from Code Pink are available here. This should ease some of the sourcing concerns expressed in the comments.
Secondly, many helpful folks in the comments have pointed out that the language quoted in the article was "attack" not "invade", which would significantly lower the bar for impeachment, so I've updated the title appropriately.
Update 2:
From the comments - for those who want to put a bit more pressure on, please add your signatures to Congressman Wexler's petition to impeach Cheney, and of course, the 1 million plus folks at impeachbush.org (many thanks to tr4nqued, gleniris, and siamesewonka).
