Just saw him on Chris Hayes. He says he's focused on his anti-gerrymandering project, but he's considering it.

That would be fabulous!

And what he said gave me the tiniest little bit of peace.

"Mueller and Rosenstein pulled the greatest end-run around Donald Trump, and no one saw it coming, and it's this: by referring this matter to the Southern District of New York, it ensures that this legal exposure and culpability between Trump and Cohen survives the dismissal of Mueller and survives the dismissal of Rosenstein.

"And why that matters is that an impeachable event does not arise out of an investigation by the Special Counsel....[T]he Mueller probe can be shut down because Trump and Cohen are now involved in this legal exposure in New York. If Trump is found to be legally culpable, that can still be an impeachable matter for the U.S. Congress."
