Headley, who is a Laskar-e-Toiba (LeT) operative is believed to be behind 26/11 Mumbai terror attacks, is expected to plead guilty in a Chicago court on Thursday, Mar 18.
With India waiting to hear about what happens at the US court, the unexpected meeting between Chidambaram and Roemer has raised a lot of questions.
Roemer has reportedly reitariated US' committment to cooperate with India on all issues pertaining to terrorism.
US' Director National Intelligence Dennis C Blair also met Union Home Minister.
The National Investigation Agency (NIA) is expected to file additional charges in the Mumbai terror attack case if Headley pleads guilty.
