According to the wikileaks cables, Chidambaram, in early 2010, discussed with the then Federal Bureau of Investigation (FBI) director Robert Mueller about his suspicion that the suspected mastermind of 26/11 Mumbai terror attack, David Coleman Headley had not acted alone.
"I have a feeling in my bones that Headley was not acting alone," stated Chidambaram while in a discussion with US officials, claimed a US embassy cable, who gave out Chidambaram's statement in the site.
The leaks also claimed that though the Government of India was happy with US' co-operation with India in handling the case of Headley, Chidambaram stressed for direct access to Headley. The cables also suggested that Chidambaram wanted access to Headley just for "appearance sake".
