The directory is published every five years and is available only to alumni of the Ivy League law school in Cambridge, Massachusetts.

Scaramucci, who left his White House post on Monday after only 11 days on the job, is a 1989 graduate of the law school. He also served as an "expert in residence" there in 2012, according to Harvard Law's website, offering finance and investment advice to students.

He founded the SkyBridge Capital investment fund in 2005 and later served as a senior official for the U.S. Export-Import Bank before being named communications director for the White House on July 21.

Scaramucci shocked many last week with an expletive-laced interview that targeted then-chief of staff Reince Priebus and White House chief strategist Steve Bannon. He later tweeted that he sometimes uses "colourful language" and pledged to refrain.
