President Obama announces Jack Lew as his nominee to replace Tim Geithner as Treasury Secretary. January 10, 2013.
And while he was at it, he made some Lew-curly-signature jokes.
"I think the only point that I want to make -- leave you with is the fact that I had never noticed Jack’s signature. And -- and when this was highlighted yesterday in the press, I considered rescinding my offer to appoint him.
Jack assures me that he is going to work to make at least one letter legible in order not to debase our currency, should he be confirmed as secretary of the treasury."
