U.S. president Barack Obama is set to nominate his chief of staff, Jacob Lew (pictured above) as the next U.S. treasury secretary later today.

Lew formerly served as the Obama budget director from 2010 to 2012 seems the likely frontrunner to succeed Geithner.

I wrote back in December that the next U.S. treasury secretary would play a greater role in setting foreign policy than the next U.S. secretary of state (U.S. senator John Kerry has been nominated for that job).

Here’s the Ezra Klein dossier on Lew.
