The luncheon meeting assumes significance as it takes place after Burns appeared at a closed-door session with lawmakers on Capitol Hill where he is expected to have answered queries from the Congressmen over the nuclear agreement.

A senior administration official has said repeatedly that several lawmakers have a number of questions on the deal and wanted more details about it. During his three-day stay in Washington, Saran will call on various lawmakers separately to present India's case. Seeking to dispel their apprehensions, he is expected to highlight New Delhi's impeccable record on non-proliferation front.
