Bloomberg's Hans Nichols reports that Obama will name Jack Lew as Treasury Secretary tomorrow.

Lew, who is currently Obama's Chief Of Staff, has been seen as the frontrunner for a long time.

Previously he was Obama's budget chief, and previous to that he was at Citi.

While Lew is seen as likely being an easy nomination, there is some GOP opposition to him.

Several Republicans said Tuesday they don’t view Lew as a man interested in hearing GOP concerns. One aide called him “tone deaf” in understanding the compromises that Republicans could accept during high-stakes talks.
