Obama’s impression on the Gandhi scion hit the internet following a review of the memoir for The New York Times by Chimamanda Ngozi Adichie.
"Rahul Gandhi has a nervous, unformed quality about him, as if he were a student who'd done the coursework and was eager to impress the teacher but deep down lacked either the aptitude or the passion to master the subject," notes the review.
The memoirs include Obama’s impressions of several American and world leaders, including Sonia Gandhi, Manmohan Singh and Vladimir Putin.
'A Promised Land' will be published on November 17 by Crown.
Obama's other books include 'Dreams from My Father', 'The Audacity of Hope' and 'Change we can Believe in'.
