This is the actual e-mail, which I'm sure you've already read for yourself instead of taking Schumer's word for things.

The extent of Rove's involvement, unless you have more documents at hand, seems to be him asking someone what's going to be done about attorneys, with a wide range of options, including allowing all of them to stay.

There is no mention this early in the game of specific attorneys, of how many would be dismissed, or what the "plan" would actually be.

However, as we all know, the mere existence of Rove's name in a document is an impeachment offense. If I was having fun cherry-picking this, I could honestly state that in January 2005, Rove put forward the option of keeping all the attorneys.
