Congress' Raashid Alvi reacted to his party leader P Chidambaram's "Wanted to retaliate after 26/11 attacks but US said avoid war" remark and said, "Does this mean he was working under US pressure? Such a statement will only benefit BJP." "Why is Chidambaram making this claim after 16 years?...If he disagreed at that time, he should have resigned," he added.
