AmEx’s Chenault Said to Be Discussed for Treasury Post

White House officials have approached American Express Co. Chief Executive Officer Kenneth Chenault about joining President Barack Obama’s second-term administration, possibly as Treasury secretary, according to two people familiar with the matter.

White House Chief of Staff Jack Lew remains the leading contender for the Treasury job, the people said. Still, consideration of Chenault among Obama’s staff may indicate the president hasn’t made a final decision on a replacement for Treasury Secretary Timothy F. Geithner, who has said he plans to leave the post.
